\(\frac{5^4\cdot 7}{2^6\cdot 5^7\cdot 7}\) का दशमलव प्रसार कितने स्थानों पर समाप्त होगा?
After how many decimal places will \(\frac{5^4\cdot 7}{2^6\cdot 5^7\cdot 7}\) terminate?
Explanation opens after your attempt
Correct Answer
C. (6)
Concept
After cancellation, the denominator becomes \(2^6\cdot 5^3\). The larger exponent is (6), so the decimal terminates after (6) places.
Why this answer is correct
The correct answer is C. (6). After cancellation, the denominator becomes \(2^6\cdot 5^3\). The larger exponent is (6), so the decimal terminates after (6) places.
Exam Tip
कटौती के बाद हर \(2^6\cdot 5^3\) बचेगा। बड़ी घात (6) है इसलिए दशमलव (6) स्थानों पर समाप्त होगा।
