यदि सरलतम हर \(q=2^7\cdot 5^7\) है तो दशमलव प्रसार के बारे में क्या निश्चित है?
If the reduced denominator is \(q=2^7\cdot 5^7\), what is certain about the decimal expansion?
Explanation opens after your attempt
Correct Answer
A. ठीक (7) स्थानों पर समाप्तTerminates exactly after (7) places
Concept
The reduced denominator is \(10^7\), so the decimal terminates exactly after (7) places. If the denominator is reduced, do not assume further cancellation.
Why this answer is correct
The correct answer is A. ठीक (7) स्थानों पर समाप्त / Terminates exactly after (7) places. The reduced denominator is \(10^7\), so the decimal terminates exactly after (7) places. If the denominator is reduced, do not assume further cancellation.
Exam Tip
सरलतम हर \(10^7\) है इसलिए दशमलव ठीक (7) स्थानों पर समाप्त होगा। सरलतम हर दिया हो तो अंश से और कटौती नहीं माननी चाहिए।
