Find the factors and group them in two sets with the same integers in both sets. The product of either set will be the square root; in this case: #75#.

Explanation:

#sqrt5625#

By a process of simple division, we can determine the factors.

#5625-:5=1125#

#1125-: 5=225#

#225-:5=45#

#45-:5=9#

#9-:3=3#

#3-:3=1#

So we have two sets of factors: #(5xx5xx3)# and #(5xx5xx3)#

The product of either set is #75#, the square root of #5625#.
