Power negative a b to the third power minus ac if a equals -2 and b equals 3 and c equals negative 8

The answer is:  " - 38 " .

Explanation:

Given:  "  −ab³ − ac ”  ;

Solve this expression when:  "a = -2 " ;  " b = 3 " ;  " c = 8 " ;

So, we plug in our given values for "a", "b" and "c" ; and solve:

    [−(2)*(3³)  − [(-2*8)]  =  (-2*27)  − (-16) = (-54) + (16) =  " -38 " .

Ibelieve the second one, but if not, the first one will do. hope this : )
