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.
