   Find the square root.  Assume that all of the variables represent positive real numbers./-121 (radical)


                      sq.rt of negative no cannot be determined 

                     we can write sq.rt of -121 as sq.rt-1 .sq.rt121

                                   sq.rt -1 = i

                                   sq.rt 121 = 11

                             sq.rt -121 = 11i
