Question

Evaluate the expression when a=−2, b=3, and c=−8. −ab3−ac=?

Answer 1

Answer:

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

Step-by-step explanation:

Consider the provided expression.

$-ab^3-ac$

Substitute the value of a=-2, b=3 and c=-8 in the above expression and solve.

$-(-2)(3)^3-(-2)(-8)$

$-(-2)(27)-(16)$

$2(27)-16$

$54-16$

$38$

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

Answer 2

-(-2)x(3)x3-(-2)x(-8)= 2
