What is the value of \(\frac{6!}{5!}+2!\)?\(\frac{6!}{5!}+2!\) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 88
Since \(6!=6\times5!\), \(\frac{6!}{5!}=6\). Also, \(2!=2\times1=2\). Therefore, \(\frac{6!}{5!}+2!=6+2=8\), so option C is correct. Option 7 may result from incorrectly taking \(2!\) as 1. Exam tip: simplify factorial fractions first by cancelling the common factorial term.क्योंकि \(6!=6\times5!\), इसलिए \(\frac{6!}{5!}=6\)। साथ ही, \(2!=2\times1=2\)। अतः \(\frac{6!}{5!}+2!=6+2=8\), इसलिए सही विकल्प C है। विकल्प 7 तब मिल सकता है जब \(2!\) को गलती से 1 मान लिया जाए। परीक्षा टिप: फैक्टोरियल वाले भिन्न में समान फैक्टोरियल पदों को पहले काटकर सरल करें।
