What is the value of (2^9\div2^7)?(2^9\div2^7) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 44
For division of powers with the same base, use \(a^m\div a^n=a^{m-n}\). Thus, \(2^9\div2^7=2^{9-7}=2^2=4\), so option D is correct. Exam tip: subtract the exponents when dividing powers with the same non-zero base; do not multiply them.समान आधार वाली घातों के भाग के लिए नियम है: \(a^m\div a^n=a^{m-n}\)। इसलिए \(2^9\div2^7=2^{9-7}=2^2=4\), अतः सही विकल्प D है। ध्यान रखें कि भाग करते समय घातों का घटाव किया जाता है, गुणा नहीं।
