To solve this problem, we'll methodically approach it by following these steps:
Now, let's execute each step in detail:
Step 1: Simplify the expression inside the parentheses .
Calculate :
Substitute back into the expression:
Step 2: Evaluate the expression .
Calculate the square:
The solution to the problem is , which corresponds to choice 2.
\( \)\( -(2)^2= \)
Because we're squaring a negative number! When you multiply , negative times negative equals positive. The negative sign is inside the parentheses that get squared.
because the negative applies after squaring. But because the negative is part of what gets squared.
Work step-by-step from the innermost operations outward. Write each step clearly: . Don't try to do multiple steps at once!
You likely forgot that squaring always gives a positive result! Remember: . The exponent 2 applies to the entire .
Yes, but be very careful with parentheses! Enter it exactly as (-(2^2))^2 to get the right answer. Missing parentheses will give you the wrong result.
