Powerful X's
Simplifying Variables With Exponents

 

 So now we can deal with an X 

 that has an exponent or a root.
 
 But what do we do with this?
 

3X2 = 12

 
 Do we try to get the 3 away from the X first?
 
 Do we try to get rid of the exponent first?
 
 To better see what you should do,
 rewrite this without any exponents.
 Use multiplication instead ...
 

3 X X = 12

 
 Does that help?
 
 The first thing we do is
 get rid of the stuff that is not an X.
 
 That means we need to lose the 3.
 
 In this problem, the 3 is multiplied times the X's
 so we need division to peel it away ...
 

 
 Now get rid of the exponent with a root ...
