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

Answer:

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

Step-by-step 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.
