What is the value of \(\frac{6!}{4!}+0!\)?\(\frac{6!}{4!}+0!\) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 3131
Since \(6!=6\times5\times4!\), \(\frac{6!}{4!}=6\times5=30\). Also, by definition, \(0!=1\). Therefore, \(\frac{6!}{4!}+0!=30+1=31\). Option 30 results if \(0!\) is not added. Exam tip: In factorial fractions, cancel common factorial terms first to simplify quickly.\(6!=6\times5\times4!\), इसलिए \(\frac{6!}{4!}=6\times5=30\)। साथ ही, परिभाषा के अनुसार \(0!=1\)। अतः \(\frac{6!}{4!}+0!=30+1=31\)। विकल्प 30 तब मिलता है जब \(0!\) को जोड़ना भूल जाएँ। परीक्षा टिप: फैक्टोरियल के भाग में समान फैक्टोरियल पदों को पहले काटकर सरल करें।
