\(\frac{2^3\cdot 5^2}{2^7\cdot 5^5}\) का दशमलव प्रसार कितने स्थानों पर समाप्त होगा?
After how many decimal places will \(\frac{2^3\cdot 5^2}{2^7\cdot 5^5}\) terminate?
Explanation opens after your attempt
Correct Answer
B. (4)
Concept
After cancellation, the denominator becomes \(2^4\cdot 5^3\). The larger exponent is (4), so the decimal terminates after (4) places.
Why this answer is correct
The correct answer is B. (4). After cancellation, the denominator becomes \(2^4\cdot 5^3\). The larger exponent is (4), so the decimal terminates after (4) places.
Exam Tip
कटौती के बाद हर \(2^4\cdot 5^3\) बचेगा। बड़ी घात (4) है, इसलिए दशमलव (4) स्थानों पर समाप्त होगा।
