What is the value of \(5!\times0!\)?\(5!\times0!\) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 120120
By definition, \(5!=5\times4\times3\times2\times1=120\) and \(0!=1\). Therefore, \(5!\times0!=120\times1=120\), so option C is correct. Option A would result from the incorrect assumption that \(0!=0\). Exam tip: always remember that \(0!=1\) because it is the value of an empty product.परिभाषा के अनुसार \(5!=5\times4\times3\times2\times1=120\) तथा \(0!=1\)। अतः \(5!\times0!=120\times1=120\), इसलिए सही उत्तर विकल्प C है। विकल्प A तब मिलता यदि \(0!\) को गलती से 0 माना जाए। परीक्षा टिप: रिक्त गुणनफल की परिभाषा के कारण हमेशा \(0!=1\) याद रखें।
