Question 1/1 Expert Mathematics Chapter 1: Real Numbers 3: Prime factorisation Class 10 Level 7

यदि किसी संख्या का अभाज्य गुणनखंड रूप \(2^6\times3^4\times5^2\) है, तो उसका वर्गमूल क्या होगा?

If a number has prime factorisation \(2^6\times3^4\times5^2\), what is its square root?

Correct Answer

A. \(2^3\times3^2\times5\)

Step 1

Concept

In square root, each prime exponent becomes half.

Step 2

Why this answer is correct

\(2^6\) becomes \(2^3\), \(3^4\) becomes \(3^2\), and \(5^2\) becomes (5).

Step 3

Exam Tip

This direct method works when all exponents are even. चरण 1: वर्गमूल लेते समय हर अभाज्य गुणनखंड की घात आधी हो जाती है। चरण 2: \(2^6\) से \(2^3\), \(3^4\) से \(3^2\), और \(5^2\) से (5) मिलेगा। चरण 3: यह विधि तभी सीधे लागू होती है जब सभी घातें सम हों।
