Question

simplify the expression below using order of operations. 1 ÷ 1 × (7² + 8)

Explanation:

Step1: Calculate the exponent

First, we handle the exponent in the expression. The exponent is \(7^2\), which means \(7\times7 = 49\). So the expression inside the parentheses becomes \(49 + 8\).

$$7^2=49$$

Step2: Simplify the parentheses

Now, we simplify the expression inside the parentheses. We add \(49\) and \(8\): \(49+8 = 57\). So the expression now is \(1\div1\times57\).

$$49 + 8=57$$

Step3: Perform the division and multiplication

Next, we perform the division and multiplication from left to right. First, \(1\div1 = 1\). Then, we multiply this result by \(57\): \(1\times57 = 57\).

$$1\div1 = 1$$

$$1\times57 = 57$$

Answer:

\(57\)
