Here are some of laws of exponent.
Any number or variable raised to 1 is equal to the number or variable itself.
`x^1 = x`
Example: `5^1 = 5`
Any number or variable raised to 0 is equal to 1.
`x^0 = 1`
Example: `3^0 = 1`
Negative exponent means fraction.
`x^-1 = 1/x`
Example: `4^-1 = 1/4`
`x^-n = 1/x^n`
Example: `5^-2 = 1/5^2 = 1/25`
You can try the link below for an image of the other rules...
