Question

i am studying my programs on this app. it does not show error when i import math function (Math.sqrt,Math.pow)without importing method java.lang.Math....?
does compilation and execution by sololearn is correct or wrong?👍

Answer 1

public class mathpowdemo
{
public static void main(String[] args) {
double a=2;
double b=3;
double c=Math.pow(a,b);
System.out.println(+c);
