Correct Answer

A. (1)

Step 1

Concept

HCF uses the smaller power of a common prime.

Step 2

Why this answer is correct

The powers of (5) are (3) and (1), so the smaller power is (1).

Step 3

Exam Tip

Recognise power (1) correctly in the answer. चरण 1: महत्तम समापवर्तक में समान अभाज्य की छोटी घात आती है। चरण 2: (5) की घातें (3) और (1) हैं, इसलिए छोटी घात (1) होगी। चरण 3: घात (1) को भी सही उत्तर में पहचानें।
