\(\sqrt{5}\) को परिमेय मानने पर \(p^2=5q^2\) मिलता है। यदि (p=5r), तो कौन-सा सरलीकरण सही है?

Assuming \(\sqrt{5}\) rational gives \(p^2=5q^2\). If (p=5r), which simplification is correct?

Explanation opens after your attempt
Correct Answer

A. \(q^2=5r^2\)

Step 1

Concept

Putting (p=5r) gives \(25r^2=5q^2\).

Step 2

Why this answer is correct

Dividing both sides by (5) gives \(q^2=5r^2\).

Step 3

Exam Tip

Reduce factors correctly during simplification. चरण 1: (p=5r) रखने पर \(25r^2=5q^2\) बनता है। चरण 2: दोनों पक्षों को (5) से भाग देने पर \(q^2=5r^2\) मिलता है। चरण 3: सरलीकरण में गुणक सही घटाएँ।

\(\sqrt{2}\) की सिद्धि में (p=2r) रखने पर \(p^2=2q^2\) से कौन सा सही सरलीकरण प्राप्त होता है?

In the proof of \(\sqrt{2}\), after putting (p=2r), which correct simplification is obtained from \(p^2=2q^2\)?

Explanation opens after your attempt
Correct Answer

A. \(q^2=2r^2\)

Step 1

Concept

If (p=2r), then \(p^2=4r^2\).

Step 2

Why this answer is correct

From \(4r^2=2q^2\), dividing both sides by (2) gives \(q^2=2r^2\).

Step 3

Exam Tip

This proves \(q^2\), and then (q), is even. चरण 1: (p=2r) रखने पर \(p^2=4r^2\) होगा। चरण 2: \(4r^2=2q^2\) से दोनों ओर (2) से भाग करने पर \(q^2=2r^2\) मिलता है। चरण 3: इससे \(q^2\) सम और फिर (q) सम सिद्ध होता है।

कौन सा विकल्प \(\sqrt{3}\) की सिद्धि में गलत सरलीकरण है?

Which option is a wrong simplification in the proof of \(\sqrt{3}\)?

Explanation opens after your attempt
Correct Answer

D. (p=3k) से \(p^2=3k^2\)From (p=3k), \(p^2=3k^2\)

Step 1

Concept

Squaring (p=3k) gives ((3k)2).

Step 2

Why this answer is correct

Its correct value is \(9k^2\), not \(3k^2\).

Step 3

Exam Tip

Do not forget to square the coefficient. चरण 1: (p=3k) को वर्ग करने पर ((3k)2) मिलता है। चरण 2: इसका सही मान \(9k^2\) है, \(3k^2\) नहीं। चरण 3: गुणांक का वर्ग न भूलें।

कौन सा कथन \(\sqrt{2}\) के प्रमाण में (p=2k) रखने के बाद गलत सरलीकरण है?

Which statement is a wrong simplification after putting (p=2k) in the proof of \(\sqrt{2}\)?

Explanation opens after your attempt
Correct Answer

D. \(p^2=2k^2\)

Step 1

Concept

If (p=2k), then (p-2=(2k)2).

Step 2

Why this answer is correct

Its correct value is \(4k^2\), not \(2k^2\).

Step 3

Exam Tip

Square the coefficient while squaring. चरण 1: (p=2k) है तो (p-2=(2k)2)। चरण 2: इसका सही मान \(4k^2\) है, \(2k^2\) नहीं। चरण 3: वर्ग करते समय गुणांक का भी वर्ग करें।

\(\sqrt{3}\) के प्रमाण में (p=3k) रखने के बाद \(9k^2=3q^2\) मिला। इसे सरल करने का सही तरीका क्या है?

In the proof for \(\sqrt{3}\), after putting (p=3k), \(9k^2=3q^2\) is obtained. What is the correct simplification?

Explanation opens after your attempt
Correct Answer

A. दोनों पक्षों को (3) से भाग देकर \(q^2=3k^2\) पानाDivide both sides by (3) to get \(q^2=3k^2\)

Step 1

Concept

In \(9k^2=3q^2\), the common factor is (3).

Step 2

Why this answer is correct

Dividing by (3) gives \(3k^2=q^2\), that is \(q^2=3k^2\).

Step 3

Exam Tip

Remove only valid common factors while simplifying. चरण 1: \(9k^2=3q^2\) में साझा गुणनखंड (3) है। चरण 2: (3) से भाग देने पर \(3k^2=q^2\), यानी \(q^2=3k^2\) मिलता है। चरण 3: सरलीकरण में केवल वैध समान गुणनखंड हटाएँ।

In the proof for \(\sqrt{5}\), after putting (x=5n), \(25n^2=5y^2\) is obtained. What is the next correct simplification?

Explanation opens after your attempt
Correct Answer

A. \(y^2=5n^2\)

Step 1

Concept

In \(25n^2=5y^2\), both sides can be divided by (5).

Step 2

Why this answer is correct

This gives \(5n^2=y^2\), that is \(y^2=5n^2\).

Step 3

Exam Tip

While simplifying, remove only the common factor, not the whole (25). चरण 1: \(25n^2=5y^2\) में दोनों पक्ष (5) से भाग दिए जा सकते हैं। चरण 2: इससे \(5n^2=y^2\), अर्थात \(y^2=5n^2\) मिलता है। चरण 3: सरलीकरण में (25) को पूरा नहीं हटाएँ, केवल समान गुणनखंड हटाएँ।

\(\sqrt{3}+2\sqrt{3}=3\sqrt{3}\).

Step 3

Exam Tip

Before adding, convert radicals into like terms if possible. चरण 1: \(\sqrt{12}=2\sqrt{3}\) है। चरण 2: \(\sqrt{3}+2\sqrt{3}=3\sqrt{3}\)। चरण 3: जोड़ से पहले वर्गमूलों को समान रूप में बदलें।

\(\sqrt{7}+\sqrt{7}\) का सरल रूप क्या है?

What is the simplified form of \(\sqrt{7}+\sqrt{7}\)?

Explanation opens after your attempt
Correct Answer

A. \(2\sqrt{7}\)

Step 1

Concept

Like radicals are added like like terms.

Step 2

Why this answer is correct

\(\sqrt{7}+\sqrt{7}=2\sqrt{7}\).

Step 3

Exam Tip

In addition, do not add the numbers inside roots to write \(\sqrt{14}\). चरण 1: समान वर्गमूलों को समान पद की तरह जोड़ा जाता है। चरण 2: \(\sqrt{7}+\sqrt{7}=2\sqrt{7}\)। चरण 3: जोड़ में अंदर की संख्याएँ जोड़कर \(\sqrt{14}\) नहीं लिखना चाहिए।

\(\sqrt{2}\times\sqrt{18}\) का मान क्या होगा?

What is the value of \(\sqrt{2}\times\sqrt{18}\)?

Explanation opens after your attempt
Correct Answer

A. (6)

Step 1

Concept

When multiplying square roots, multiply the numbers inside.

Step 2

Why this answer is correct

\(\sqrt{2}\times\sqrt{18}=\sqrt{36}=6\).

Step 3

Exam Tip

The product of two irrational numbers can sometimes be rational. चरण 1: वर्गमूलों के गुणन में अंदर की संख्याएँ गुणा होती हैं। चरण 2: \(\sqrt{2}\times\sqrt{18}=\sqrt{36}=6\)। चरण 3: दो अपरिमेय संख्याओं का गुणनफल कभी-कभी परिमेय हो सकता है।

\(\sqrt{2}\times\sqrt{3}\) किसके बराबर है?

What is \(\sqrt{2}\times\sqrt{3}\) equal to?

Explanation opens after your attempt
Correct Answer

B. \(\sqrt{6}\)

Step 1

Concept

While multiplying square roots, multiply the numbers inside.

Step 2

Why this answer is correct

\(\sqrt{2}\times\sqrt{3}=\sqrt{6}\), which is irrational.

Step 3

Exam Tip

In multiplication, multiply the inside numbers; do not add them. चरण 1: वर्गमूलों के गुणन में अंदर की संख्याएँ गुणा होती हैं। चरण 2: \(\sqrt{2}\times\sqrt{3}=\sqrt{6}\), जो अपरिमेय है। चरण 3: गुणा में अंदर की संख्याएँ गुणा करें, जोड़ नहीं।

\(\sqrt{2}\) और \(\sqrt{8}\) का योग किसके बराबर है?

What is the sum of \(\sqrt{2}\) and \(\sqrt{8}\)?

Explanation opens after your attempt
Correct Answer

A. \(3\sqrt{2}\)

Step 1

Concept

\(\sqrt{8}=2\sqrt{2}\).

Step 2

Why this answer is correct

\(\sqrt{2}+2\sqrt{2}=3\sqrt{2}\).

Step 3

Exam Tip

Simplify radicals before adding them. चरण 1: \(\sqrt{8}=2\sqrt{2}\) है। चरण 2: \(\sqrt{2}+2\sqrt{2}=3\sqrt{2}\)। चरण 3: जोड़ने से पहले वर्गमूलों को सरल करें।

\(\sqrt{2}\times\sqrt{8}\) का मान क्या है?

What is the value of \(\sqrt{2}\times\sqrt{8}\)?

Explanation opens after your attempt
Correct Answer

A. (4)

Step 1

Concept

\(\sqrt{2}\times\sqrt{8}=\sqrt{16}\).

Step 2

Why this answer is correct

\(\sqrt{16}=4\), so the value is rational.

Step 3

Exam Tip

While multiplying square roots, multiply the numbers inside the roots. चरण 1: \(\sqrt{2}\times\sqrt{8}=\sqrt{16}\)। चरण 2: \(\sqrt{16}=4\), इसलिए मान परिमेय है। चरण 3: वर्गमूलों को गुणा करते समय अंदर की संख्याएँ गुणा करें।

अनुक्रम \(\sqrt{3},\sqrt{12},\sqrt{27},\sqrt{48}\) के लिए सही कथन कौन सा है?

Which statement is correct for \(\sqrt{3},\sqrt{12},\sqrt{27},\sqrt{48}\)?

Explanation opens after your attempt
Correct Answer

A. समांतर श्रेणी है और \(d=\sqrt{3}\)It is an AP and \(d=\sqrt{3}\)

Step 1

Concept

The terms become \(\sqrt{3},2\sqrt{3},3\sqrt{3},4\sqrt{3}\). In exams, simplify radicals before finding differences.

Step 2

Why this answer is correct

The correct answer is A. समांतर श्रेणी है और \(d=\sqrt{3}\) / It is an AP and \(d=\sqrt{3}\). The terms become \(\sqrt{3},2\sqrt{3},3\sqrt{3},4\sqrt{3}\). In exams, simplify radicals before finding differences.

Step 3

Exam Tip

पद \(\sqrt{3},2\sqrt{3},3\sqrt{3},4\sqrt{3}\) बनते हैं। परीक्षा में मूलों को सरल करके ही अंतर निकालें।
