\(\frac{55}{2\cdot 5^2\cdot 11^2}\) का दशमलव प्रसार कैसा होगा?
What type of decimal expansion will \(\frac{55}{2\cdot 5^2\cdot 11^2}\) have?
Explanation opens after your attempt
Correct Answer
B. असांत आवर्तीNon-terminating recurring
Concept
\(55=5\cdot 11\).
Why this answer is correct
After cancellation, the denominator becomes \(2\cdot 5\cdot 11\). Since (11) remains, the decimal is non-terminating recurring.
Exam Tip
After partial cancellation, always check the remaining factors. चरण 1: \(55=5\cdot 11\) है। चरण 2: कटौती के बाद हर \(2\cdot 5\cdot 11\) बचेगा। (11) बचने के कारण दशमलव असांत आवर्ती होगा। चरण 3: आंशिक कटौती के बाद बचे हुए गुणनखंडों को जरूर जाँचें।
