सबसे छोटा धनात्मक (n) क्या है जिसके लिए (n!) संख्या \(2^9\cdot3^3\cdot5^2\) से विभाज्य हो?
What is the smallest positive (n) for which (n!) is divisible by \(2^9\cdot3^3\cdot5^2\)?
Explanation opens after your attempt
C. (11)
Concept
(11!) has exponent (8) of (2), so \(2^9\) is not satisfied. Therefore the minimum is (12).
Why this answer is correct
The correct answer is C. (11). (11!) has exponent (8) of (2), so \(2^9\) is not satisfied. Therefore the minimum is (12).
Exam Tip
(11!) में (2) की घात (8) नहीं बल्कि (8) से अधिक (8) ही होती है, पर \(2^9\) के लिए (12!) चाहिए। इसलिए सही न्यूनतम (12) है।
