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

Answer 1

To evaluate the expression a5 − bc + 4a ÷ c when a = 2, b = 3, and c = 8, we substitute these values into the expression:

a5 − bc + 4a ÷ c
= 2^5 − (3)(8) + 4(2) ÷ 8

Using the order of operations (PEMDAS/BODMAS), we perform the multiplication and division before the addition and subtraction:

= 32 - 24 + 8/8
= 32 - 24 + 1
= 8 + 1
= 9

Therefore, when a = 2, b = 3, and c = 8, the expression a5 − bc + 4a ÷ c evaluates to 9.
