What is the simplified value of \(\frac{6!}{4!}\)?\(\frac{6!}{4!}\) का सरल मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 3030
Since \(6!=6\times5\times4!\), \(\frac{6!}{4!}=\frac{6\times5\times4!}{4!}=6\times5=30\). Therefore, 30 is correct. The value 120 is \(5!\), not the value of this quotient. Exam tip: In factorial division, expand the larger factorial only up to the smaller factorial and cancel common terms.क्योंकि \(6!=6\times5\times4!\), इसलिए \(\frac{6!}{4!}=\frac{6\times5\times4!}{4!}=6\times5=30\)। अतः सही उत्तर 30 है। 120, \(5!\) का मान है, इसलिए यह इस भागफल का मान नहीं है। परीक्षा टिप: फैक्टोरियल के भाग में बड़े फैक्टोरियल को छोटे फैक्टोरियल तक फैलाकर समान पदों को काटें।
