First to convert a
to a double you can use Double.parseDouble.
has methods for taking the square root and square.
There is no symbol for square root or square.

PS: As Keith said, there are no Java operators for squares or roots, so do
make the mistake of using the bitwise "exclusive or," as in x^2. Instead, you should use methods in the Math class.
