A number, x, multiplied by itself once is x^2. It is NOT x.
The number, x, multiplied by itself twice is then x^3.
The number, x, multiplied by itself three times is then x^4.
Thus x is the 4th root of 27.
So x = 27^(1/4) = +/- 2.2795 and +/- 2.2795*i where i is the imaginary square root of -1.

I think you mean the symbol for the power to which a number is raised. The two is called "squared"- that is when a number is multiplied times itself- 3 squared is 9. You will also see the small 3- "Cubed"- number times itself, times itself. 3 cubed is 27- 3x3x3.
