Exponets

1. b^x * b^y = b^ x + y

2. b^x / b^y = b^ x-y

3. any number raised to the 0 = 1

4. (ab)^x = a^x b^x

5. (a/b)^x = a^x/b^x

6. (b^x) ^y = b^xy

7. nth root of a = a^1/n

8. nth root of a^y = a^y/n

9. x^-n = 1/x^n

10. a * b^x = cant simplify (pemdas)

11. (-a)^2 = positive number

12. -a^2 = negative number
