यदि \(\frac{231}{2\cdot3\cdot5^2\cdot7\cdot11}\) को सरलतम रूप में लिखा जाए, तो दशमलव प्रसार कैसा होगा?
If \(\frac{231}{2\cdot3\cdot5^2\cdot7\cdot11}\) is written in lowest form, what type of decimal expansion will it have?

Correct Answer
A. समाप्तTerminating
Concept
After cancelling \(231=3\cdot7\cdot11\), the denominator left is \(2\cdot5^2\). Therefore the decimal terminates.
Why this answer is correct
The correct answer is A. समाप्त / Terminating. After cancelling \(231=3\cdot7\cdot11\), the denominator left is \(2\cdot5^2\). Therefore the decimal terminates.
Exam Tip
\(231=3\cdot7\cdot11\) कटने के बाद हर में \(2\cdot5^2\) बचता है। इसलिए दशमलव समाप्त होगा।
