Question
Evaluate the expression at specific values of their variables.(1 point)
Evaluate a5 − bc + 4a ÷ c when a = 2, b = 3, and c = 8.

1 answer

To evaluate the expression at the specific values of the variables, substitute the given values into the expression:

a = 2, b = 3, c = 8

a5 = 2^5 = 32
bc = 3*8 = 24
4a = 4*2 = 8
c = 8

Now substitute these values into the expression:

a5 − bc + 4a ÷ c
= 32 − 24 + 8 ÷ 8
= 32 - 24 + 1
= 9

Therefore, the expression evaluates to 9 when a = 2, b = 3, and c = 8.
