1. Write code that prints the square root of the value in the variable num rounded to 4 decimal places. Assume that num already has a value and that the math module has been imported.

System. out. printf ("The square root is %.4f/n", sqrt);

Explanation:

In Java programming language using the print format method of System. out One can specify the the number of decimal places. In this case to 4 decimal places.

See a complete code snippet below

public class num1 {

public static void main (String[] args) {

double num = 5;

double sqrt = Math. sqrt (5);

System. out. printf ("The square root is $%.4f/n", sqrt);

}

}
