Simplify the following expressions:

z^8

z^8

it is supposed to be a fraction

Z^8/z^8 = 1

when exponents are in a fraction w the same coefficient on the top and bottom (z) and you need to simplify it, you subtract the bottom exponent from the top exponent.

In this case 8-8=0

In addition, since z^8 and z^8 are the same value, they cancel each other out. A number divided by the same number is 1. For example: 7/7=1

So, it's the same for z^8/z^8

The answer is 1
