What is the value of (5!-3!)?(5!-3!) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 114114
Using factorials, \(5!=5\times4\times3\times2\times1=120\) and \(3!=3\times2\times1=6\). Therefore, \(5!-3!=120-6=114\). The value 120 is only \(5!\); it does not include subtracting \(3!\). Exam tip: Evaluate each factorial first, then perform the indicated operation.क्रमगुणित के अनुसार, \(5!=5\times4\times3\times2\times1=120\) और \(3!=3\times2\times1=6\)। अतः \(5!-3!=120-6=114\)। विकल्प 120 केवल \(5!\) का मान है; इसमें \(3!\) घटाया नहीं गया है। परीक्षा टिप: क्रमगुणित वाले व्यंजक में पहले प्रत्येक क्रमगुणित का मान निकालें, फिर दी गई संक्रिया करें।
