यदि किसी सरलतम भिन्न का हर \(2^4\cdot 5^2\) है, तो दशमलव प्रसार में कितने स्थान होंगे?

Explanation opens after your attempt
Correct Answer

B. (4)

Step 1

Concept

The denominator has power (4) of (2) and power (2) of (5).

Step 2

Why this answer is correct

Decimal places in a terminating decimal equal the larger exponent, which is (4).

Step 3

Exam Tip

If the denominator is already reduced, do not assume further cancellation. चरण 1: हर में (2) की घात (4) और (5) की घात (2) है। चरण 2: सांत दशमलव के स्थान बड़ी घात के बराबर होते हैं, यानी (4)। चरण 3: सरलतम हर होने पर अंश से कोई और कटौती नहीं माननी चाहिए।
