Question

evaluate.
12 + 8² ÷ 4

Explanation:

Step1: Calculate the exponent

First, we need to evaluate the exponent \(8^2\). By the definition of exponentiation, \(8^2 = 8\times8 = 64\). So the expression becomes \(12 + 64\div4\).

Step2: Perform the division

Next, we perform the division operation. According to the order of operations (PEMDAS/BODMAS), division comes before addition. So we calculate \(64\div4 = 16\). Now the expression is \(12 + 16\).

Step3: Perform the addition

Finally, we add the two numbers. \(12+16 = 28\).

Answer:

28
