In order to get the answer to this question you have to remember that if the exponent is positive you need to move to the right, and if the exponent is negative you got to move to the left.

- Positive so move to the right 8 times....


Therefore the answer is "490000000."
Hope this helps!

Altho' I can easily guess what you're supposed to do here, I must point out that you haven't included the instructions for this problem.
I'll help you by example. Let's look at the first problem:
"Evaluate 6(z-1) at z-4."
Due to "order of operations" rules, we must do the work inside the parentheses FIRST. Replace the z inside (z-1) with "-4". We obtain
6(-4-1) = 6(-5) = -30 (answer.)
Your turn. Try the next one. If it's unclear, as questions.
2.16 x 10 to the power of -4
X² - 4x - 77 = 0
( x + 7) ( x - 11)
x + 7 = 0
x - 11 = 0
x = -7
x = 11
Answer:
-4 = ?
Step-by-step explanation:
<u>Step 1: Substitute -1 for x</u>
7x^3 + 5x^2 - 2 = ?
7(-1)^3 + 5(-1)^2 - 2 = ?
7(-1) + 5(1) - 2 = ?
-7 + 5 - 2 = ?
-4 = ?
Answer: -4 = ?
