What is the value of (2^5 \div 2^2)?
Advertisement
Answer and explanation
Correct answer: 8
When powers with the same base are divided, subtract the exponents: \(2^5 \div 2^2 = 2^{5-2} = 2^3 = 8\). Therefore, 8 is correct. Getting 16 may result from incorrectly adding the exponents. Exam tip: use \(a^m \div a^n = a^{m-n}\) for the same base.
