into
I am kind of cheating by saying
and working back from that, but I am sure there is a better way.
Any help much appreciated!

Is this what you want as a format ? If yes, then I chose 27 because it is the nearest number to 25 that is a perfect cube (that has an integer as its cubic root, because we are considering the cubic root here). In the previous question, mathaddict chose 32 because it is the nearest number to 33 that has an integer as its fifth root. Do you get the idea ?
