Look for perfect squares that divide into 73:

The first few perfect squares are :

#2^2=4# Does not go into #73# without remainder

#3^2=9# Does not go into #73# without remainder

#4^2=16# is even, we already checked 4 doesn't go in evenly

#5^2 = 25# Does not go into #73# without remainder

#6^2# is even

#7^2=49#

#9^2 = 81# is greater than #73#

#73# is not divisible by a perfect square, so #sqrt73# cannot be simplified.
