Answer:
124
Step-by-step explanation:
(ab)^2 + (b^3 - a^2)
Let a = -2 and b = 4
(-2 *4)^2 + (4^3 - (-2)^2)
Parentheses first
(-8)^2 + (4^3 - (-2)^2)
Then the exponents in the parentheses
(-8)^2 + (64 - 4)
Subtract in the parentheses
(-8)^2 + (60)
Exponents
64 + 60
(-2*4)2+(4×3--2×2)
(-8)2+(12--4)
-16+16
=0
