What is the value of (9^5 \div 9^4)?(9^5 \div 9^4) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 99
For division of powers with the same base, use \(a^m \div a^n = a^{m-n}\). Therefore, \(9^5 \div 9^4 = 9^{5-4} = 9^1 = 9\). Hence, option D is correct. Exam tip: subtract the exponents when the bases are the same; do not subtract or divide the bases.समान आधार वाली घातों के भाग के नियम के अनुसार, \(a^m \div a^n = a^{m-n}\)। इसलिए \(9^5 \div 9^4 = 9^{5-4} = 9^1 = 9\)। अतः सही उत्तर विकल्प D है। ध्यान रखें कि भाग करते समय घातों को घटाया जाता है, आधारों को नहीं।
