Evaluate 2(-4)^3+3(-4)^2-72*-4

Problem

2*(−4)^3+3*(−4)^2−72*(−4)

Solution

1. Evaluate the exponents by calculating the powers of −4

(−4)^3=−64

(−4)^2=16

2. Substitute these values back into the expression.

2*(−64)+3*(16)−72*(−4)

3. Perform the multiplications for each term.

2*(−64)=−128

3*(16)=48

−72*(−4)=288

4. Combine the terms by adding and subtracting from left to right.

−128+48=−80

−80+288=208

Final Answer

2*(−4)^3+3*(−4)^2−72*(−4)=208
