Evaluate a^5−bc+4a ÷c when a=2, b=3, and c=8 .

Answer 1

To evaluate the expression a^5 - bc + 4a ÷ c when a = 2, b = 3, and c = 8, we substitute the values into the expression.

First, let's find a^5:
a^5 = 2^5 = 32

Next, let's find 4a ÷ c:
4a ÷ c = 4(2) ÷ 8 = 8 ÷ 8 = 1

Now, let's substitute the found values into the expression:

32 - bc + 1

Substituting the values of b and c:
32 - (3)(8) + 1

Multiplying 3 and 8:
32 - 24 + 1

Simplifying the expression:
32 - 24 + 1 = 8 + 1 = 9

Therefore, when a = 2, b = 3, and c = 8, the expression a^5 - bc + 4a ÷ c evaluates to 9.
