or
Step-by-step explanation:
No need for a calculator.
Assuming that the equation is in the form , we can plug in points to get our equation. For ease, let's use (1,18) and (2,21). When plugging these points in, we get
. Now let's divide the equations to get rid of
:
. Now that we have
, we can plug in the value we just calculated to solve for
:
, and solving for
, we get
.
So the
This equation in decimal form (rounded to the nearest thousandth) is .

Hello there!
amd
Let me start with 8^-2
8^-2 = 1/8 * 8
8^-2 = 1/64
which equals to 0.015625 in decimal
8^ 0 = 1
Yep, that's the answer! Easy, isn't? Well you may have been wondering why 8^0 is equal to 1.
I quoted an explanation online that says: Think of "multiplication" as always including an extra "1" as a multiplier.
So it'd be like
8^ 0
8/8 = 1
Remember: Whenever a number has an exponent 0, the answer MUST be 1.
Thus,
8^0 is greater. As you can see, it is equal to 1, while the other one is equal to 0.01
I'm terrible at explaining stuff. I hope you find this answer somehow helpful :)
