$(4$ pts$)$ Find a minimum SOP expression for m$0+$m$2+$m$8+$m$9+$m$10+$m$15+$D$1+$D$3+$D$6+$D$7+$D$11$

$(6$ pts$)$ Given

$f=\frac{A}{b}ar(B)\frac{+}{b}ar\frac{A}{b}ar\frac{B}{b}ar(D)+$ABD$\frac{+}{b}ar\frac{A}{b}ar(B)\frac{C}{b}ar(D)+\frac{A}{b}ar(B)C\frac{+}{b}ar\frac{B}{b}ar(C)D+$ABCD

$g\frac{?}{b}=ar(B)\frac{C}{b}ar(D)\frac{+}{b}ar\frac{B}{b}ar\frac{C}{b}ar(D)+$ACD$+\frac{A}{b}ar(B)D+$ACD$\frac{+}{b}ar\frac{A}{b}ar\frac{B}{b}ar(C)+A\frac{B}{b}ar(C)D$

Does $f=g?($show why or why not$)$
