  2. public static void main(String[] args)
  3. {
  4. double a = 0.57;
  5. double b = 0.25;
  6. System. out. println(Math. pow(a, b)); // return a^b i.e. 5^2.
  7. }
  8. }

How do you write squared in Java?

Squaring a number in Java can be accomplished in two ways. One is by multiplying the number by itself. The other is by using the Math. pow() function, which takes two parameters: the number being modified and the power by which you’re raising it.

How do you write an exponent in Java?


pow(base, exponent)” with the number you want raised to the power where it says “base” and the power you want it raised to where it says “power.” You can make the result an integer by using (int) before the function, but without this, it automatically returns a “double” value and takes parameters as “double” too.
