Evaluate a5−bc+4a ÷c when a=2 , b=3 , and c=8 .
To evaluate the expression a5 - bc + 4a ÷ c when a = 2, b = 3, and c = 8, we substitute the values in the expression:
2(5) - 3(8) + 4(2) ÷ 8
Now, we solve the expressions within parentheses:
10 - 24 + 8 ÷ 8
Then, we perform the division:
10 - 24 + 1
Next, we perform the subtraction:
-14 + 1
Finally, we perform the addition:
-13
Therefore, the value of the expression a5 - bc + 4a ÷ c when a = 2, b = 3, and c = 8 is -13.
