Answer:

56

Explanation:

Use the Order of Operations:


(9 - 2)^(2) - [ {2}^(2) - {3}^(2)] + 2 = {7}^(2) - [4 - 9] + 2 = \\ \\ 49 - -5 + 2 = 49 + 5 + 2 = 56

According to the Order of Operations, you evaluate everything on grouping symbols, then the exponents [indices, roots, etcetera], then Division & Multiplication from left to right, then finally, Subtraction & Addition from right to left [or left to right as long as you know what you are doing correctly].

I am joyous to assist you anytime.
