What is the value of (3^5 \div 3^3)?
Advertisement
Answer and explanation
Correct answer: 9
When powers with the same base are divided, subtract the exponents: \(3^5 \div 3^3 = 3^{5-3}=3^2=9\). Therefore, 9 is the correct answer. Getting 27 would result from applying the exponent rule incorrectly. Exam tip: remember \(a^m \div a^n=a^{m-n}\), where \(a\ne0\).
