Question

Write code statements that prompt for and read a double value from the user, and then print the result of raising that value to the fourth power. Output the results to three decimal places.

Answer 1

Following are the code in Java Language:

Scanner sc = new Scanner(System.in); // create a instance of scanner class

DecimalFormat frmt = new DecimalFormat("0.###"); // create a instance of // DecimalFormat class

System.out.println ("Enter the value: ");

double number = scan.nextDouble(); // Read the value by thje user

System.out.println (fmmt.format(Math.pow(number, 4))); // display the value

Step-by-step explanation:

Following are the description of the code

• Create an instance scanner class i.e "sc".

• Create an instance of DecimalFormat class i.e "frmt".

• Read the value by the user in the "number" variable of type double by using the nextDouble()method.

• Finally, display the value by using System.out.println method. In this, we call the method format. The Math.pow() function is used to calculating the power up to the fourth value.
