What is the value of \(2!\times3!\times4!\)?\(2!\times3!\times4!\) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 288288
Here, \(2!=2\), \(3!=3\times2\times1=6\), and \(4!=4\times3\times2\times1=24\). Therefore, \(2!\times3!\times4!=2\times6\times24=288\). Option D, \(48\), is only \(2!\times4!\) and misses \(3!\). Exam tip: Evaluate each factorial separately before multiplying.यहाँ \(2!=2\), \(3!=3\times2\times1=6\) और \(4!=4\times3\times2\times1=24\) है। अतः \(2!\times3!\times4!=2\times6\times24=288\)। विकल्प D में केवल \(2!\times4!\) का गुणनफल \(48\) है; उसमें \(3!\) शामिल नहीं है। परीक्षा टिप: फैक्टोरियल के प्रत्येक मान को पहले अलग-अलग लिखकर फिर गुणा करें।
