Step-by-step solution

To solve this problem, we'll methodically approach it by following these steps:

  • Step 1: Simplify the expression inside the parentheses.
  • Step 2: Evaluate the power applied to the result from Step 1.

Now, let's execute each step in detail:

Step 1: Simplify the expression inside the parentheses ((2)2) (-(2)^2) .

Calculate (2)2 (2)^2 :

22=4 2^2 = 4

Substitute back into the expression:

(2)2=4 -(2)^2 = -4

Step 2: Evaluate the expression (4)2 (-4)^2 .

Calculate the square:

(4)2=16 (-4)^2 = 16

The solution to the problem is 16 16 , which corresponds to choice 2.
