Expert Mathematics Real Numbers Class 10 Level 13

यदि \(x=\sqrt{a}\) अपरिमेय है और (a<50) धनात्मक पूर्णांक है, तो कौन-सा (a) उपयुक्त नहीं है?

If \(x=\sqrt{a}\) is irrational and (a<50) is a positive integer, which (a) is not suitable?

Explanation opens after your attempt
Correct Answer

C. (36)

Step 1

Concept

\(\sqrt{a}\) is irrational only when (a) is not a perfect square.

Step 2

Why this answer is correct

(36) is a perfect square and \(\sqrt{36}=6\), so it is not suitable.

Step 3

Exam Tip

Quickly identify perfect squares among the options. चरण 1: \(\sqrt{a}\) अपरिमेय तभी होगा जब (a) पूर्ण वर्ग न हो। चरण 2: (36) पूर्ण वर्ग है और \(\sqrt{36}=6\), इसलिए यह उपयुक्त नहीं है। चरण 3: विकल्पों में पूर्ण वर्ग को तुरंत पहचानें।
