What is the value of (4!+2!)?(4!+2!) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 2626
Here, 4! = 4 × 3 × 2 × 1 = 24 and 2! = 2 × 1 = 2. Therefore, 4! + 2! = 24 + 2 = 26. The value 28 can result from an incorrect evaluation of 4!; evaluate each factorial first and then add. Exam tip: the symbol ! denotes the factorial of the number immediately before it.यहाँ 4! = 4 × 3 × 2 × 1 = 24 और 2! = 2 × 1 = 2 है। अतः 4! + 2! = 24 + 2 = 26। 28 तब मिलता यदि 4! को गलती से 26 मान लिया जाए; फैक्टोरियल का मान पहले निकालकर फिर जोड़ें। परीक्षा टिप: ! केवल उसके ठीक पहले वाली संख्या का फैक्टोरियल दर्शाता है।
