Exponents look like this: x^n.
To simplify an exponent, you multiply x n times.
Here's some rules:
When you multiply, you add exponents.
x^n * x^m = x^(n+m)
When you divide, you subtract exponents.
x^n/x^m = x^(n-m)
x^n/x^m = x^(n-m)
Distributin them exponents:
(x*y)^n = x^n * y^n
Also in division:
(x/y)^n = x^n/y^n
And when you raise it to the 0 power, you get 1. Always.
(pi+687698757865897698578658768976-2+6565646*767676767/9-2)^0 = 1
There's some other stuff too but I'm pretty sure everybody else took notes too.
