            The general form of a complex number is a + b i

Complex Numbers:

            i =

          i = -1

          i = -

          i = 1

          i =

          i = -1         ……

Example:  Simplify.

1.)  i                         2.)  i                         3.)                    4.)                   5.)   

6.)                    7.)                               8.) 

9.)                                     10.)                    

Rationalize the denominator.
