343 = 7 cubed, so it's not the square of an integer. (It's almost exactly the square of 18.52)
Two further thoughts:
No number ending in 2, 3, 7 or 8 can be the square of an integer;
A cube can also be a square only if the original number was a square.
eg (22)3 = 64 which is (23)2. The law of powers means that the cube of x squared is x6
and the square of x cubed is also x6.
Try this: if x to the power y - y to the power x = 1, what are x and y?
