I am currently learning the basic math functions and I am struggling to get this output for my homework. I think the wording is just making me more and more confused. Thanks in advance for your help! Here is the problem layout:

Z = 7

Use the Math methods and the System.out.println statement to display:

- the square root of z squared plus 1
- Output desired: 7.0710678118654755
- My output: 8

My code: public class tester {

public static void main(String[] args) { int z = 7; System.out.println(Math.pow(Math.sqrt(z), 2) + 1); }

}

## Answer

“the square root of z squared plus 1” means √(*z*^{2}+1).

You are currently calculating (√*z*)^{2}+1 — which incidentally is the same as *z*+1. Hence why you’re getting 8.
