Easy Mathematics Chapter 1: Real Numbers Class 10 Level 17

यदि \(a^2=2b^2\), तो \(a^2\) किस संख्या से निश्चित रूप से विभाज्य है?

If \(a^2=2b^2\), by which number is \(a^2\) definitely divisible?

Explanation opens after your attempt
Correct Answer

A. (2)

Step 1

Concept

The right side of the equation is \(2b^2\).

Step 2

Why this answer is correct

So \(a^2\) has factor (2) and is divisible by (2).

Step 3

Exam Tip

Use the factor to decide divisibility. चरण 1: समीकरण में दाईं ओर \(2b^2\) है। चरण 2: इसलिए \(a^2\) में (2) गुणनखंड है और वह (2) से विभाज्य है। चरण 3: गुणनखंड देखकर विभाज्यता का निष्कर्ष लें।
