$2\mathrm{.}28$ LAB: Using math functions

Given three floating$-$point numbers $x,y,$ and $z,$ output $x^z,x^{y^2},$ the absolute value of $y,$ and the square root of $(xy{)}^z.$ Output each floating$-$point value with two digits after the decimal point, which can be achieved as follows: printf$("\%0\mathrm{.}21$f$",$ yourvalue$)$;
