How can (13!) be written using (11!)?(13!) को (11!) की सहायता से कैसे लिखेंगे?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(13\times12\times11!\)\(13\times12\times11!\)
By the definition of factorial, \(13!=13\times12\times11\times10\times\cdots\times1\). Since \(11!=11\times10\times\cdots\times1\), we get \(13!=13\times12\times11!\). In \(13\times11!\), the factor \(12\) is missing. Exam tip: Expand the larger factorial only up to the given smaller factorial.क्रमगुणित के अनुसार \(13!=13\times12\times11\times10\times\cdots\times1\)। यहाँ \(11!=11\times10\times\cdots\times1\) है, इसलिए \(13!=13\times12\times11!\)। विकल्प \(13\times11!\) में \(12\) का गुणनखंड छूट जाता है। परीक्षा टिप: बड़े क्रमगुणित को दिए गए छोटे क्रमगुणित तक क्रमशः विस्तार करें।
