Rational Exponents

This week we learned a section in chapter 5 which deals with rational exponents. This section is a easy and not that hard at all.

Formulas:
A(t)=A0b^(t/k)
-A0 is starting point
-b is halfing, doubling, ect
-t is time and k is time it takes to get to b

Examples:
3rd root of square root of x= x^1/3

(16/100)^1/2= square root of 16/square root of 100 which can be simplified to 2/5

27^2x=3^2
(3^3)^2x=3^2
3^6x=3^2
6x=2
x=1/3
Basically if you know your rules and the formula this section will be easy..
