Answer:
The value of the expression when a=−2, b=3, and c=−8 is 38.
Step-by-step explanation:
Consider the provided expression.
[tex]-ab^3-ac[/tex]
Substitute the value of a=-2, b=3 and c=-8 in the above expression and solve.
[tex]-(-2)(3)^3-(-2)(-8)[/tex]
[tex]-(-2)(27)-(16)[/tex]
[tex]2(27)-16[/tex]
[tex]54-16[/tex]
[tex]38[/tex]
Hence, the value of the expression when a=−2, b=3, and c=−8 is 38.
