Question

evaluate the expression (3 + 2)² + 4·5. next, evaluate groups. (3 + 2)² + 4·5 = 5² + 4·5 = □ + ?

Explanation:

Step1: Evaluate \(5^2\)

To find \(5^2\), we use the definition of exponentiation, where \(a^2 = a\times a\). So \(5^2 = 5\times5 = 25\).

Step2: Evaluate \(4\cdot5\)

Using the multiplication operation, \(4\cdot5 = 20\).

Answer:

The first box is \(25\) and the second box (the "?") is \(20\). So the expression becomes \(25 + 20\), and if we were to fully evaluate it, the result is \(45\), but for the boxes as per the question, the first is \(25\) and the second is \(20\).
