What is the value of (81\div3^2)?

Answer and explanation

Correct answer: 9

According to the order of operations, evaluate the exponent first: \(3^2=9\). Then \(81\div 9=9\), so option C is correct. Option A (3) may result from confusing the base with the value of the expression, while option B ignores the division. Exam tip: In such expressions, calculate exponents before performing division.
