we get that Melissa is trying to solve the expression ( 3 + 4) ² - 9.

We are given that:

Melissa is simplifying an expression using the order of operations which can be addition, subtraction, multiplication or division.

She adds 3 and 4, squares the result, and subtracts 9.

We will first add 3 and 4:

3 + 4

Now we will square them:

( 3 + 4) ²

Now, we will subtract 9 from it:

( 3 + 4) ² - 9

So, the expression becomes:

( 3 + 4) ² - 9

Therefore, we get that Melissa is trying to solve the expression ( 3 + 4) ² - 9.
