Explanation opens after your attempt
Correct Answer

B. \(\sqrt{12}\) और \(\sqrt{3}\)\(\sqrt{12}\) and \(\sqrt{3}\)

Step 1

Concept

\(\sqrt{12}=2\sqrt{3}\) and \(\sqrt{3}\) are both irrational.

Step 2

Why this answer is correct

\(\frac{\sqrt{12}}{\sqrt{3}}=\sqrt{4}=2\), which is rational.

Step 3

Exam Tip

In quotients, check whether the value inside the root becomes a perfect square. चरण 1: \(\sqrt{12}=2\sqrt{3}\) और \(\sqrt{3}\) दोनों अपरिमेय हैं। चरण 2: \(\frac{\sqrt{12}}{\sqrt{3}}=\sqrt{4}=2\), जो परिमेय है। चरण 3: भागफल में मूल के अंदर का भाग पूर्ण वर्ग बन रहा है या नहीं, यह देखें।

Question 2/2 Hard Mathematics Chapter 1: Real Numbers 5: Irrational numbers Class 10 Level 14

कौन-सा विकल्प दो अलग-अलग अपरिमेय संख्याओं का उदाहरण है जिनका भागफल परिमेय है?

Which option is an example of two different irrational numbers whose quotient is rational?

Explanation opens after your attempt
Correct Answer

C. \(\frac{\sqrt{5}}{\sqrt{20}}\)

Step 1

Concept

\(\sqrt{5}\) and \(\sqrt{20}=2\sqrt{5}\) are both irrational and different.

Step 2

Why this answer is correct

\(\frac{\sqrt{5}}{\sqrt{20}}=\frac{\sqrt{5}}{2\sqrt{5}}=\frac{1}{2}\), which is rational.

Step 3

Exam Tip

A common irrational factor can cancel in a quotient. चरण 1: \(\sqrt{5}\) और \(\sqrt{20}=2\sqrt{5}\) दोनों अपरिमेय हैं और अलग-अलग हैं। चरण 2: \(\frac{\sqrt{5}}{\sqrt{20}}=\frac{\sqrt{5}}{2\sqrt{5}}=\frac{1}{2}\), जो परिमेय है। चरण 3: भागफल में समान अपरिमेय गुणनखंड कट सकता है।
