What is the value of \(\frac{5!+4!}{4!}\)?\(\frac{5!+4!}{4!}\) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 66
Since \(5!=5\times4!\), \(\frac{5!+4!}{4!}=\frac{5\times4!+4!}{4!}=\frac{6\times4!}{4!}=6\). Therefore, the correct answer is 6. Option 5 would result if the additional \(4!\) in the numerator were ignored. Exam tip: In factorial fractions, factor out the common factorial before simplifying.क्योंकि \(5!=5\times4!\), इसलिए \(\frac{5!+4!}{4!}=\frac{5\times4!+4!}{4!}=\frac{6\times4!}{4!}=6\)। अतः सही उत्तर 6 है। विकल्प 5 तब मिलता यदि अंश में केवल \(5!\) होता और \(4!\) जोड़ा न गया होता। परीक्षा टिप: फैक्टोरियल वाले भिन्नों में समान फैक्टरियल को बाहर निकालकर पहले सरल करें।
