what is the square root of 36

If you want a decimal approximation, use the calculator; if you want it in reduced form, write it as a number times perfect squares.

First divide out 100's:  1 800 000  =  180 x 100 x 100

Divide up 180; it is divisible by 4 and by 9, leaving a 5.

                                 1 800 000  =  5 x 4 x 9 x 100 x 100

                                √1 800 000  =  √5 x √4 x √9 x √100 x √100

                                                   =  √5 x 2 x 3 x 10 x 10

                                                   =  600√5
