Easy Mathematics Chapter 1: Real Numbers Class 10 Level 17

यदि \(a^2=5b^2\), तो (a) को किस रूप में लिखा जा सकता है?

If \(a^2=5b^2\), in which form can (a) be written?

Explanation opens after your attempt
Correct Answer

A. (a=5k), जहां (k) पूर्णांक है(a=5k), where (k) is an integer

Step 1

Concept

From \(a^2=5b^2\), \(a^2\) is divisible by (5).

Step 2

Why this answer is correct

Therefore (a) is also divisible by (5), so (a=5k).

Step 3

Exam Tip

After divisibility, write the number using that factor. चरण 1: \(a^2=5b^2\) से \(a^2\) (5) से विभाज्य है। चरण 2: इसलिए (a) भी (5) से विभाज्य है और (a=5k) लिखा जा सकता है। चरण 3: विभाज्यता मिलने पर संख्या को उसी गुणनखंड के रूप में लिखें।
