There is also a pow() function
a little bit of google goes along way:

isn't it Math.pow(i,2)
and the 2 means what power the i is raised to?

The qualifying path to the proper class library depends on what libraries you have imported...Math is the class library...pow() is the function within that library. And yes, in the example of pow(a,B), a is raised to the power of b.

Necro'd thread.......
And, no, I don't think we can have a good square root symbol show up on the output.

extended ASCII code 251 (at least the sheet says it is) is a square root symbol. Why not just display that?
I am getting the wrong ASCII code though. Does Java have problems with extended ASCII?
int i = 4; char square = 251; double j = math.pow(i,1/2); System.out.println(square + "" i + " is " + j);
