What is the value of \(\frac{5!}{4!}+1\)?\(\frac{5!}{4!}+1\) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 66
Since \(5!=5\times4!\), we get \(\frac{5!}{4!}=5\). Therefore, the given expression is \(5+1=6\). It is not necessary to evaluate both factorials completely; \(4!\) cancels directly. Exam tip: For consecutive factorials, write the larger factorial in terms of the smaller one before simplifying.क्योंकि \(5!=5\times4!\), इसलिए \(\frac{5!}{4!}=5\)। अतः दिया गया व्यंजक \(5+1=6\) है। \(5!\) और \(4!\) को अलग-अलग पूरा निकालना आवश्यक नहीं है; \(4!\) को सीधे काटा जा सकता है। परीक्षा टिप: क्रमागत फैक्टोरियल में बड़े फैक्टोरियल को छोटे फैक्टोरियल के रूप में लिखकर सरल करें।
