What is \(\frac{8!}{8}\) equal to?\(\frac{8!}{8}\) किसके बराबर है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(7!\)\(7!\)
Since \(8!=8\times7!\), \(\frac{8!}{8}=\frac{8\times7!}{8}=7!\). Therefore, \(7!\) is correct. Choosing \(8!\) is incorrect because dividing by 8 removes the factor 8. Exam tip: use \(n!=n\times(n-1)!\) to simplify such expressions quickly.क्योंकि \(8!=8\times7!\), इसलिए \(\frac{8!}{8}=\frac{8\times7!}{8}=7!\)। अतः सही विकल्प \(7!\) है। \(8!\) को उत्तर मानना गलत है, क्योंकि भाजक 8 से भाग देने पर एक गुणनखंड हट जाता है। परीक्षा टिप: \(n!=n\times(n-1)!\) का प्रयोग करके ऐसे प्रश्न तुरंत हल करें।
