RATIONALIZATION

It is customary that we do not leave radicals in denominators.
We multiple the fraction by a form of one to remove the radical from the denominator.
Remember multiplying a number by one or a form of one does not change the number's value.
Here is an example of rationalization: 
=    =    =   =   =   = 

If we were to change    to exponential form (5/4^1/3)

(5/4^1/3)(4^2/3/4^2/3) =

5(4^2/3)/4^{1/3 + 2/3} =

5(16^1/3)/4^3/3 = 

5(8^1/32^1/3)/4 =

10(2^1/3)/4 = 

5(2^1/3)/2  =


There is another form of problem that require rationalization. This is a problem such as     This is solve by multiplying the fraction by the denominator's conjugate       in the form of one. That is  

  =
