i need help

look for perfect squares less than 54     49   36   25   16  9   4   1  0

   subtract them from 54 to see if any results in a perfect square

54-49 = 5     so if sqrt x = 5     would be one  x = 25

54-36=18             sqrtx=18                              x = 324

            29                                                               841

            38                                                               1444

            45                                                              2025
