What is the value of (4^4 \div 4^2)?
Answer and explanation
Correct answer: 16
When powers with the same base are divided, subtract the exponents: \(4^4 \div 4^2 = 4^{4-2} = 4^2 = 16\). Therefore, 16 is the correct answer. 64 equals \(4^3\), which may result from subtracting the exponents incorrectly. Exam tip: use \(a^m \div a^n = a^{m-n}\), where \(a \ne 0\).
