Как квадрат значение в JavaScript
// Use Math.pow(a,b); where a is your value and b is the exponent
var num = Math.pow(4, 2);
//num returns 16

// Use Math.pow(a,b); where a is your value and b is the exponent
var num = Math.pow(4, 2);
//num returns 16Math.pow(base, exponent);
Math.pow(2, 4);
// Outputs 16
// The same as going 2^4, 2 to the power of 4let number = 2;
let exponent = 3;
//using the exponent operator
console.log( number ** exponent);
// using the Math library
console.log( Math.pow(number, exponent);
// these will both output 8 Math.pow(base, exponent);
Math.pow(2, 4);import java.lang.*;
public class MathDemo {
public static void main(String[] args) {
//what is Math.pow(3, 2)?
double x = 3;
double y = 2;
System.out.println("Math.pow(" + x + "," + y + ")=" + Math.pow(x, y));
}
}
//the Output is 9console.log(Math.pow(2, 4)); // 16
console.log(Math.pow(3, 3)); // 27
// Negative bases to fractional exponents return NaN:
console.log(Math.pow(-7, 1/3)); // NaN
