What is the value of ( \frac{12!}{9!}-3\cdot\frac{11!}{8!} )?( \frac{12!}{9!}-3\cdot\frac{11!}{8!} ) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: (132)(132)
The first part is (1320), and the second is (3\cdot990=2970), so the value is negative and the options are incorrect. Always check signs and multipliers.पहला भाग (1320) और दूसरा (3\cdot990=2970) नहीं; सही दूसरा (3\cdot990) है, अतः मान ऋणात्मक होगा और विकल्प त्रुटिपूर्ण हैं।
