I'm writing a program to calculate the wind chill based on a temperature and wind speed entered by the user. The formula to calculate wind chill is

Wind Chill = 35.74 + 0.6215T - 35.75V0.16 + 0.4275TV0.16

My current code is

import java.util.Scanner;
import java.util.Math;
public class WindChill {

public static void main(String[] args) {
	
	//Declare variables

	double windChill;
	double temperature;
	int    windSpeed;

//Ask the user for temperature and wind speed

System.out.print("Enter the temperature (Fahrenheit):  ");
	Scanner input = new Scanner (System.in);
	temperature = input.nextDouble();

System.out.print("Enter the wind speed(mph):  ");
	windSpeed = input.nextInt();

	
//Display the wind chill value

windChill = (35.74+(0.6215*temperature)) - (Math.pow(35.75*windSpeed,0.16)) + (Math.pow(0.4275*temperature*windSpeed,0.16));	
System.out.print("The wind chill index is " + windChill);
}

}

I get an error in the IDE on line 2 that says "the import java.util.Math could not be resolved". Also, when I try to run the program, I get the error message

"Exception in thread "main" java.lang.Error: Unresolved compilation problem: 

at WindChill.main(WindChill.java:6)

I checked my installed JREs and I am using JRE7. Can anybody tell me what is wrong?

import java.util.Scanner; public class FormulaEvaluator { /* *Evaluate the expression. * *@param args Command line arguments (not used). */

public static void main(String[] args) {

  Scanner userInput = new Scanner(System.in);
  String name = "";
  double x = 0.0;
  double value = 0.0;
  //Prompt the user for a value of x
  System.out.print("Enter a value for x: "); 
  x = userInput.nextDouble();
  //Calculate the value of x using user input
  value = Math.pow(x);
  System.out.print("Result:" + value);

} }

My error message: FormulaEvaluator.java:27: error: method pow in class Math cannot be applied to given types; value = Math.pow(x); ^ required: double,double found: double reason: actual and formal argument lists differ in length 1 error

We're having to solve a long formula as a project but when I try to raise the x variable, which is the user input, to a power it doesn't compile and gives the error. It works fine when using Math.abs so I'm not really sure what's going on. Thanks in advance.
