Compute: val $=|w^x|$

Ex: If the input is $4\mathrm{.}002\mathrm{.}00,$ then the output is:

val$=16\mathrm{.}00$public class MathMethods $\{$ Scanner scnr $=$ new Scanner$($System$.$in$)$; double x; w $=$ scnr$.$nextDouble$()$; System.out.printf$("$val $=\%\mathrm{.}2$f

$",$ val$)$; $//$ Outputs val with $2$ decimal places$\}$
