−(−2)4+(−2)2=
To solve this problem, let's evaluate the expression −(−2)4+(−2)2 step-by-step:
Step 1: Calculate (−2)4.
Since the exponent is even, (−2)4=((−2)×(−2)×(−2)×(−2)).
Calculating more explicitly:
(−2)×(−2)=4,
4×(−2)=−8,
−8×(−2)=16.
Thus, (−2)4=16.
Step 2: Negate the result from step 1.
−(−2)4=−(16)=−16.
Step 3: Calculate (−2)2.
Since the exponent is even, (−2)2=(−2)×(−2)=4.
Step 4: Add the results from step 2 and step 3.
−16+4=−12.
Therefore, the final result is −12.
