\(\sqrt{5}\) 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।

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।

सरल रूप में किसी परिमेय संख्या का भाजक (q) किस रूप में हो तो दशमलव समाप्त होगा?

In lowest form, what form should the denominator (q) of a rational number have for the decimal to terminate?

Explanation opens after your attempt
Correct Answer

A. \(2^m5^n\)

Step 1

Concept

For a terminating decimal, the denominator must be made only from (2) and (5).

Step 2

Why this answer is correct

So its form is \(2^m5^n\).

Step 3

Exam Tip

(m) or (n) may be zero, so only (2) or only (5) is also allowed. चरण 1: समाप्त दशमलव के लिए भाजक केवल (2) और (5) से बनना चाहिए। चरण 2: इसलिए उसका रूप \(2^m5^n\) होता है। चरण 3: (m) या (n) शून्य भी हो सकते हैं, इसलिए केवल (2) या केवल (5) भी चलेगा।

\(\sqrt{3}\) 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।
