## Exponents Basic Rules

### Rules of Exponents
The nine laws for exponents are:
- x<sup>1</sup> = x
- x<sup>0</sup> = 1
- x<sup>-m</sup> = 1/x<sup>m</sup>
- x<sup>m</sup> * x<sup>n</sup> = x<sup>m+n</sup>
- x<sup>m</sup> / x<sup>n</sup> = x<sup>m-n</sup>
- (x<sup>m</sup>)<sup>n</sup> = x<sup>m*n</sup>
- (x / y)<sup>2</sup> = x<sup>2</sup> / y<sup>2</sup>
- x<sup>m/n</sup> = <sup>n</sup>√(x<sup>m</sup>)

## 0<sup>0</sup> = ?

0<sup>0</sup> has no correct answear but is generally taken as 1. More information about it can be found [here](https://en.wikipedia.org/wiki/Zero_to_the_power_of_zero).
