To solve the problem of evaluating , we will follow these steps:
Let's work through these steps:
Step 1: Calculate . We know that when squaring a negative number, the result becomes positive: .
Step 2: Now apply the negative sign to this result. The expression is , which equals .
Therefore, the solution to the problem is .
\( \)\( -(2)^2= \)
The negative sign outside the parentheses isn't part of what gets squared! Only gets squared to equal 36, then we apply the outer negative sign to get .
In , only gets squared first. In , we simplify inside parentheses first to get . Parentheses placement matters!
Use PEMDAS! First handle what's in parentheses , then apply the negative sign outside. Think of it as two separate steps.
Not always! It depends on the expression. is negative, but would be positive because we're negating a negative result.
Without parentheses, would mean . The result is the same here, but parentheses make the order crystal clear and prevent confusion!
