Which option has value (720)?किस विकल्प का मान (720) है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: \(6!\)\(6!\)
\(6! = 6 \times 5 \times 4 \times 3 \times 2 \times 1 = 720\), so \(6!\) is the correct option. \(5! = 120\), making it a close but incorrect distractor. Exam tip: if you remember \(5! = 120\), multiply it by 6 to find \(6! = 720\) quickly.\(6! = 6 \times 5 \times 4 \times 3 \times 2 \times 1 = 720\), इसलिए सही विकल्प \(6!\) है। \(5! = 120\) होता है, इसलिए वह निकटतम लेकिन गलत विकल्प है। परीक्षा टिप: \(5! = 120\) याद होने पर उसे 6 से गुणा करके \(6! = 720\) जल्दी ज्ञात किया जा सकता है।
