Answer 1

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.
