What is the value of (9^3 \div 3^4)?(9^3 \div 3^4) का मान क्या है?
Answer and explanationउत्तर और व्याख्या
Correct answer:सही उत्तर: 99
Rewrite 9 as 3^2: 9^3=(3^2)^3=3^6. Using the quotient rule for powers with the same base, 3^6 \div 3^4=3^{6-4}=3^2=9. Therefore, option A is correct. Exam tip: when dividing powers with the same base, subtract the exponents.9 को 3^2 के रूप में लिखें: 9^3=(3^2)^3=3^6। अब समान आधार वाले घातों के भाग का नियम लगाएँ: 3^6 \div 3^4=3^{6-4}=3^2=9। इसलिए सही उत्तर विकल्प A है। परीक्षा युक्ति: भाग करते समय समान आधार होने पर घात घटाए जाते हैं।
