Needing help drawing the circuits for $a,b,$ and $c$ on paper.

Problem $2$ Comparators

Implement a logic circuit with $8$ inputs $(x_2{x}_1{x}_0{y}_2{y}_1{y}_0)$ and $3$ outputs $($GEL$),$

$($a$)$ Using AND, OR$,$ EXOR gates and inverters. $($b$)$ MUX and any additional gates needed, $($c$)$ PLAs and any additional gates.
