Question

use the order of operations to evaluate this expression. enter the number that belongs in the green box. 3(2 - 1)^2 • 3 = ?

Explanation:

Step1: Solve inside the parentheses

First, we solve the expression inside the parentheses: \(2 - 1 = 1\). So the expression becomes \(3(1)^{2} \cdot 3\).

Step2: Evaluate the exponent

Next, we evaluate the exponent. We have \((1)^{2} = 1\). Now the expression is \(3 \cdot 1 \cdot 3\).

Step3: Multiply from left to right

Now we multiply from left to right. First, \(3 \cdot 1 = 3\), and then \(3 \cdot 3 = 9\).

Answer:

9
