यदि \(\frac{a}{b}\) सरलतम रूप में है और \(b=2^4\cdot5^3\cdot7\), तो इसका दशमलव प्रसार कैसा होगा?
If \(\frac{a}{b}\) is in lowest form and \(b=2^4\cdot5^3\cdot7\), what type of decimal expansion will it have?
Explanation opens after your attempt
Correct Answer
A. अनवसानी आवर्तीNon-terminating recurring
Concept
The denominator contains (7), so the decimal will not terminate and being rational it will recur. In exams decide after checking the denominator in lowest form.
Why this answer is correct
The correct answer is A. अनवसानी आवर्ती / Non-terminating recurring. The denominator contains (7), so the decimal will not terminate and being rational it will recur. In exams decide after checking the denominator in lowest form.
Exam Tip
हर में (7) है, इसलिए दशमलव समाप्त नहीं होगा और परिमेय होने से आवर्ती होगा। परीक्षा में हर को सरलतम रूप में देखकर निर्णय लें।
