What is the value of (7^4 \div 7^2)?(7^4 \div 7^2) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 4949
When powers with the same base are divided, subtract the exponents: \(7^4 \div 7^2 = 7^{4-2} = 7^2 = 49\). Therefore, 49 is correct. 343 is \(7^3\), so it does not result here. Exam tip: use \(a^m \div a^n = a^{m-n}\) only when the non-zero bases are the same.समान आधार वाली घातों के भाग में घातांक घटाए जाते हैं: \(7^4 \div 7^2 = 7^{4-2} = 7^2 = 49\)। इसलिए सही उत्तर 49 है। 343, \(7^3\) का मान है, जो यहाँ नहीं आएगा। परीक्षा टिप: \(a^m \div a^n = a^{m-n}\) नियम केवल समान, शून्येतर आधार के लिए लागू करें।
