Step-by-step explanation:

If we use PEMDAS to solve the following question:

We solve for parentheses first.

(2+ 8) = 10

We then solve for the exponent

4^2 = 16

We then subtract

16 - 10 = 6

Step-by-step explanation:

Step 1: Define

4² - (x + 8)

x = 2

Step 2: Simplify

1. Evaluate exponents:                    16 - (x + 8)
2. Distribute negative:                      16 - x - 8
3. Combine like terms:                     8 - x

Step 3: Evaluate

1. Substitute in x:                    8 - 2
2. Subtract:                              6
