Evaluate the expression when a=−2, b=3, and c=−8.

−ab^3 − ac =

Answer 1

38

Explanation:

You want the value of the expression -ab³ -ac for (a, b, c) = (-2, 3, -8).

Evaluation

Put the values where the corresponding variables are and do the arithmetic.

-ab³ -ac = -(-2)(3³) -(-2)(-8) = 2·27 -16 = 54 -16 = 38

The value of the expression is 38.
