Math.pow() is a function that is provided to us by Java. Here, it takes 2 parameters. When I pass in 2 and j, it does exponentiation (known as "power") as 2 to the j-th power. For example, Math.pow(3,5) = 3 * 3 * 3 * 3 * 3.
Also, Math.pow() returns a double instead of an int. We "cast" it to an integer by putting
