The problem is to evaluate the expression $7^2 + 125$.

1. Problem Description

The problem is to evaluate the expression $7^2 + 125$.

2. Solution Steps

First, we need to calculate $7^2$. This means $7$ multiplied by itself.

$7^2 = 7 \times 7 = 49$

Now, we substitute this value back into the original expression:

$7^2 + 125 = 49 + 125$

Finally, we add the two numbers:

$49 + 125 = 174$
