To evaluate the expression 8k - h^3 + 8y ÷ r when k=4, h=2, y=5, and r=8:
First, substitute the given values into the expression:
8(4) - 2^3 + 8(5) ÷ 8
Next, simplify each part of the expression:
32 - 8 + 40 ÷ 8
Then, perform the division:
32 - 8 + 5
Finally, calculate the remaining addition and subtraction:
24 + 5 = 29
So, when k=4, h=2, y=5, and r=8, the value of the expression is 29.
