Answer:
The answer is +16
Step-by-step explanation:
Based on the question given (-2)^4
It means -2 appears in four places
That is (-2×-2)×(-2×-2)
Remember that- ×- =+
Therefore opening the first bracket
-2×-2=+4
Opening the second bracket
-2×-2=+4
Lastly bringing the two values together
+4×+4=+16
Therefore the answer is +16
