Expert Mathematics Chapter 1: Real Numbers Class 10 Level 14

यदि \(x=\frac{\sqrt{3}}{\sqrt{2}}\), तो \(x^2\) और (x) की प्रकृति के बारे में सही कथन कौन-सा है?

If \(x=\frac{\sqrt{3}}{\sqrt{2}}\), which statement about \(x^2\) and (x) is correct?

Explanation opens after your attempt
Correct Answer

A. (x) अपरिमेय है और \(x^2\) परिमेय है(x) is irrational and \(x^2\) is rational

Step 1

Concept

\(x=\sqrt{\frac{3}{2}}\), which is irrational because \(\frac{3}{2}\) is not a perfect square of a rational number.

Step 2

Why this answer is correct

\(x^2=\frac{3}{2}\), which is rational.

Step 3

Exam Tip

The square of an irrational number can sometimes be rational. चरण 1: \(x=\sqrt{\frac{3}{2}}\) है, जो अपरिमेय है क्योंकि \(\frac{3}{2}\) परिमेय पूर्ण वर्ग नहीं है। चरण 2: \(x^2=\frac{3}{2}\), जो परिमेय है। चरण 3: किसी अपरिमेय संख्या का वर्ग कभी-कभी परिमेय हो सकता है।
