Correct Answer

A. 22

Step 1

In a perfect square, all exponents are even.

Step 2

Why this answer is correct

The powers of 2 and 11 are odd.

Step 3

Exam Tip

Multiplying by \(2\times11=22\) makes both powers even. चरण 1: पूर्ण वर्ग में सभी घातें सम होती हैं। चरण 2: 2 की घात 7 और 11 की घात 3 विषम हैं। चरण 3: \(2\times11=22\) से गुणा करने पर दोनों घातें सम हो जाएंगी।
