$2\mathrm{.}27$ LAB: Using math functions

Given three floating$-$point numbers $x,y,$ and $z,$ output $x^z,x^{y^z},$ the absolute value of $y,$ and the square root of $(xy{)}^z.$

Ex: If the input is:

$5\mathrm{.}0,6\mathrm{.}5,3\mathrm{.}2$

the output is:

$172\mathrm{.}466,1\mathrm{.}29951e+279,6\mathrm{.}5,262\mathrm{.}43$
