Answer:
-4^3 + 2× -4^2 - (-4) + 5 = -23/1 = -23
Step-by-step explanation:
Exponentiation: 4 ^ 3 = 64
Unary minus: -(the result of step No. 1) = -64
Exponentiation: (-4) ^ 2 = 16
Multiple: 2 * the result of step No. 3 = 2 * 16 = 32
Add: the result of step No. 2 + the result of
= -64 + 32 = -32
Subtract: the result of step No. 5 - (-4) = -32 - (-4) = -28
Add: the result of step No. 6 + 5 = -28 + 5 = -23
