This expression cannot be simplified further.

Explanation:

You look for perfect squares that can go inside this number. The perfect squares are : #1#, #4#, #9#, #16#, #25#, #36#... it continues infinitely but since we have already passed the desired number of #30#, I will stop here.

#1# does not count since you are just dividing by #1#, which is basically the same as doing nothing.

Since #4#, #9#, #16#, #25# are not factors of #30#, or any other perfect square, this expression cannot be simplified further.
