What is the value of \(\frac{11!}{10!}\)?\(\frac{11!}{10!}\) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 1111
Since \(11!=11\times10!\), \(\frac{11!}{10!}=\frac{11\times10!}{10!}=11\). The value 110 would result from multiplying 11 by 10, but here the entire \(10!\) is cancelled. Exam tip: use \(\frac{n!}{(n-1)!}=n\) directly.क्योंकि \(11!=11\times10!\), इसलिए \(\frac{11!}{10!}=\frac{11\times10!}{10!}=11\)। विकल्प 110, \(11\times10\) करने पर मिलता है, लेकिन यहाँ \(10!\) से पूरा भाग दिया गया है। परीक्षा टिप: \(\frac{n!}{(n-1)!}=n\) सीधे लिख सकते हैं।
