Just use ANDs and ORs. Two-level optimization uses only AND (or NAND) and OR
(or NOR) gates. XORs and XNORs are quite expensive to implement in CMOS,
relative to NANDs and NORs.

You don't.

No. We will cover that on Tuesday and then I'll move that onto the next
homework assignment.

You should be able to do Problems 1-7. Don't do 8-10.
