Evaluate the expression at specific value of their variables

Evaluate : a^5 - bc + 4a divided by c when a=2, b=3, and c=8

1 answer

To evaluate the given expression when a=2, b=3, and c=8, we substitute these values into the expression.

First, calculate a^5:
a^5 = 2^5 = 32

Next, calculate 4a:
4a = 4*2 = 8

Finally, substitute the values into the expression:
(32 - bc + 8) / c

Substitute b=3 and c=8:
(32 - 3*8 + 8) / 8

Simplify the numerator:
(32 - 24 + 8) / 8

Combine like terms:
16/8

Simplify the fraction:
2

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