To evaluate the expression a^5 - bc + 4a ÷ c when a = 2, b = 3, and c = 8, we substitute these values into the expression:
a^5 - bc + 4a ÷ c
(2)^5 - (3)(8) + 4(2) ÷ 8
Calculating each part of the expression:
(2)^5 = 32
(3)(8) = 24
4(2) = 8
8 ÷ 8 = 1
Now we can substitute these values back into the expression:
32 - 24 + 1
Calculating this expression:
32 - 24 + 1 = 9
Therefore, when a = 2, b = 3, and c = 8, the expression a^5 - bc + 4a ÷ c has a value of 9.
