$3.(5$ points$)$ Draw the combinational circuit for the function below $($do NOT simplify draw it exactly as it is defined$).$ Because diagrams can be drawn very differently $($left$-$to$-$right, top$-$to$-$bottom, etc$),$ each individual gate should be labelled with the

logic it supplies, for example

$x+y-$

$x\frac{+}{b}ar((xy+z))\frac{+}{b}ar(z)(x+y)$
