What is the value of (9^2 \div 9^2)?
Answer and explanation
Correct answer: 1
Using the law of exponents, subtract the exponents when dividing powers with the same base: \(9^2 \div 9^2 = 9^{2-2} = 9^0 = 1\). Therefore, the correct answer is 1. Although 81 is the value of \(9^2\), here \(9^2\) is divided by itself. Exam tip: remember that \(a^0=1\) for every non-zero number \(a\).
