Roots (calculator)

This calculator will calculate n-that square root of a given number. For example, the square root of 81 is the number that when multiplied by itself, we get just the number 81. Thus, the square root of 81 is the number 9, because 9 · 9 = 81. Tip: the calculator also supports fractions, so if you want to calculate n-the square root where $n = \frac23$, type 2/3 (i.e. use a slash) in the "square root" field.
