POTENCIA Y RAÍZ EN ANDROID

Función potencia

Para elevar un número x a la potencia y, se emplea pow(x, y)

System.out.println("pow(10.0, 3.5) es " + Math.pow(10.0,3.5));

package desktop;

import java.io.*;

public class GetPowerExample

{

public static void main(String args[])

{

BufferedReader baseNum = new BufferedReader(new InputStreamReader(System.in));

BufferedReader powNum = new BufferedReader(new InputStreamReader(System.in));

try

{

System.out.println("Enter a base number : ");

double n = Double.parseDouble(baseNum.readLine());

System.out.println("Enter power : ");

double p = Double.parseDouble(powNum.readLine());

double result = Math.pow(n, p);

System.out.println(n+" raised to the power of "+p+" = "+result);

}

catch(Exception e)

{

System.out.println(e);

}

}

}

Función raíz cuadrada

Para hallar la raíz cuadrada de un número, se emplea la función sqrt

System.out.println("La raíz cuadrada de " + x + " is " + Math.sqrt(x));

package com.example.raiz

import java.lang.Math;

public class Punto

{

protected int x, y;

public Punto ( int x, int y )

{

this.x = x;

this.y = y;

}

// Devuelve la distancia al eje de coordenadas

public float distancia()

{

return Math.sqrt(Math.pow(x,2.0)+Math.pow(y,2.0));

}

}

Función potencia

Para elevar un número x a la potencia y, se emplea pow(x, y)

System.out.println("pow(10.0, 3.5) es " + Math.pow(10.0,3.5));

package desktop;

import java.io.*;

public class GetPowerExample

{

public static void main(String args[])

{

BufferedReader baseNum = new BufferedReader(new InputStreamReader(System.in));

BufferedReader powNum = new BufferedReader(new InputStreamReader(System.in));

try

{

System.out.println("Enter a base number : ");

double n = Double.parseDouble(baseNum.readLine());

System.out.println("Enter power : ");

double p = Double.parseDouble(powNum.readLine());

double result = Math.pow(n, p);

System.out.println(n+" raised to the power of "+p+" = "+result);
