Question

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

−ab3−ac=?

Answer 1

the anwser would be -2 because -2*3*3-2*8 equals -2

Answer 2

The value of the expression when a=−2, b=3, and c=−8 is 38.

Explanation:

Consider the provided expression.

`-ab^3-ac`

We need to solve the expression when a=−2, b=3, and c=−8.

Substitute the respective values in the provided expression.

`-(-2)(3)^3-(-2)(-8)`

Simplify the expression.

`(2)(27)-(2)(8)`

`54-16`

`38`

Hence, the value of the expression when a=−2, b=3, and c=−8 is 38.
