कौन-सा विकल्प \(\sqrt{45}\) और \(2\sqrt{5}\) के अंतर को सही बताता है?

Which option correctly gives the difference between \(\sqrt{45}\) and \(2\sqrt{5}\)?

Explanation opens after your attempt
Correct Answer

A. \(\sqrt{5}\)

Step 1

Concept

\(\sqrt{45}=3\sqrt{5}\).

Step 2

Why this answer is correct

The difference is \(3\sqrt{5}-2\sqrt{5}=\sqrt{5}\), which is irrational.

Step 3

Exam Tip

For like surds, subtract only the coefficients. चरण 1: \(\sqrt{45}=3\sqrt{5}\) है। चरण 2: अंतर \(3\sqrt{5}-2\sqrt{5}=\sqrt{5}\), जो अपरिमेय है। चरण 3: समान मूल वाले पदों में केवल गुणांक घटाएँ।

यदि \(x=\sqrt{8}+\sqrt{18}\), तो \(\frac{x}{\sqrt{2}}\) का मान क्या है?

If \(x=\sqrt{8}+\sqrt{18}\), what is the value of \(\frac{x}{\sqrt{2}}\)?

Explanation opens after your attempt
Correct Answer

A. (5)

Step 1

Concept

\(\sqrt{8}=2\sqrt{2}\) and \(\sqrt{18}=3\sqrt{2}\).

Step 2

Why this answer is correct

\(x=5\sqrt{2}\), so \(\frac{x}{\sqrt{2}}=5\).

Step 3

Exam Tip

Division is easier after combining like surds. चरण 1: \(\sqrt{8}=2\sqrt{2}\) और \(\sqrt{18}=3\sqrt{2}\)। चरण 2: \(x=5\sqrt{2}\), इसलिए \(\frac{x}{\sqrt{2}}=5\)। चरण 3: समान मूल वाले पदों को जोड़ने के बाद भाग देना आसान होता है।

कौन-सा विकल्प \(\frac{\sqrt{12}+\sqrt{27}}{\sqrt{3}}\) का सही मान देता है?

Which option gives the correct value of \(\frac{\sqrt{12}+\sqrt{27}}{\sqrt{3}}\)?

Explanation opens after your attempt
Correct Answer

A. (5)

Step 1

Concept

Write \(\sqrt{12}=2\sqrt{3}\) and \(\sqrt{27}=3\sqrt{3}\).

Step 2

Why this answer is correct

The numerator is \(5\sqrt{3}\), so \(\frac{5\sqrt{3}}{\sqrt{3}}=5\).

Step 3

Exam Tip

Combine like surds before division. चरण 1: \(\sqrt{12}=2\sqrt{3}\) और \(\sqrt{27}=3\sqrt{3}\) लिखें। चरण 2: ऊपर का योग \(5\sqrt{3}\) है, इसलिए \(\frac{5\sqrt{3}}{\sqrt{3}}=5\)। चरण 3: भाग से पहले समान मूल वाले पदों को जोड़ें।

कौन-सा विकल्प \(\sqrt{50}+\sqrt{72}-\sqrt{98}\) का सही सरल रूप है?

Which option is the correct simplified form of \(\sqrt{50}+\sqrt{72}-\sqrt{98}\)?

Explanation opens after your attempt
Correct Answer

A. \(4\sqrt{2}\)

Step 1

Concept

\(\sqrt{50}=5\sqrt{2}\), \(\sqrt{72}=6\sqrt{2}\), and \(\sqrt{98}=7\sqrt{2}\).

Step 2

Why this answer is correct

\(5\sqrt{2}+6\sqrt{2}-7\sqrt{2}=4\sqrt{2}\).

Step 3

Exam Tip

Once all terms are like surds, add or subtract only the coefficients. चरण 1: \(\sqrt{50}=5\sqrt{2}\), \(\sqrt{72}=6\sqrt{2}\), और \(\sqrt{98}=7\sqrt{2}\)। चरण 2: \(5\sqrt{2}+6\sqrt{2}-7\sqrt{2}=4\sqrt{2}\)। चरण 3: सभी पद समान मूल में बदल जाएँ तो केवल गुणांक जोड़ें या घटाएँ।

यदि \(x=\sqrt{7}+\sqrt{28}\), तो \(\frac{x^2}{7}\) का मान क्या है?

If \(x=\sqrt{7}+\sqrt{28}\), what is the value of \(\frac{x^2}{7}\)?

Explanation opens after your attempt
Correct Answer

A. (9)

Step 1

Concept

\(\sqrt{28}=2\sqrt{7}\), so \(x=3\sqrt{7}\).

Step 2

Why this answer is correct

(x-2=\(3\sqrt{7}\)2=63), hence \(\frac{x^2}{7}=9\).

Step 3

Exam Tip

Combine like surds before squaring. चरण 1: \(\sqrt{28}=2\sqrt{7}\), इसलिए \(x=3\sqrt{7}\)। चरण 2: (x-2=\(3\sqrt{7}\)2=63), अतः \(\frac{x^2}{7}=9\)। चरण 3: वर्ग करने से पहले समान मूल वाले पद जोड़ना सरल रहता है।

यदि \(x=\sqrt{11}+\sqrt{44}\), तो (x) का सरल रूप और प्रकृति क्या है?

If \(x=\sqrt{11}+\sqrt{44}\), what is the simplified form and nature of (x)?

Explanation opens after your attempt
Correct Answer

A. \(3\sqrt{11}\), अपरिमेय\(3\sqrt{11}\), irrational

Step 1

Concept

\(\sqrt{44}=\sqrt{4\times11}=2\sqrt{11}\).

Step 2

Why this answer is correct

Hence \(x=\sqrt{11}+2\sqrt{11}=3\sqrt{11}\), and \(\sqrt{11}\) is irrational.

Step 3

Exam Tip

For like surds, add only the coefficients, not the numbers inside the roots. चरण 1: \(\sqrt{44}=\sqrt{4\times11}=2\sqrt{11}\) होता है। चरण 2: इसलिए \(x=\sqrt{11}+2\sqrt{11}=3\sqrt{11}\), और \(\sqrt{11}\) अपरिमेय है। चरण 3: समान मूल वाले पदों में केवल गुणांक जोड़ें, मूल के अंदर की संख्या नहीं।

Add the coefficients of like surds.

Step 2

Why this answer is correct

\(\sqrt{3}+2\sqrt{3}=3\sqrt{3}\), and \(\sqrt{3}\) is irrational.

Step 3

Exam Tip

Coefficients add; the number inside the radical remains unchanged. चरण 1: समान मूल वाले पदों के गुणांक जोड़े जाते हैं। चरण 2: \(\sqrt{3}+2\sqrt{3}=3\sqrt{3}\), और \(\sqrt{3}\) अपरिमेय है। चरण 3: गुणांक जुड़ते हैं, मूल के अंदर की संख्या नहीं बदलती।
