Hi I'm having a hard time with my homework, could you please explain me to how to do them? My professor is not very helpful, and the textbook does not explain in a very easy way

4) Simplify the following Boolean function F, together with the don't-care conditions d, and then express the simplified function in sum-of-minterms form F(z, y, z)-S(0, 1, 4, 5, 6) d(z, y, z)- (2, 3, 7) F (A, B, C, D)(0, 6, 8, 13, 14) d (A, B, C, D)-(2, 4, 10) F (A, B, C, D) S(5, 6, 7, 12, 14, 15,) F (A, B, C, D)- (4, 12, 7, 2, 10,) d (A, B, C, D)-(3, 9, 11, 15) d(A, B, C, D)(0, 6, 8) 5) Draw (a) a NAND logic diagram that implements the complement of the following function: F (A, B, C, D) S(0, 1, 2, 3, 6, 10, 11, 14), and (b) repeat for a NOR logic diagram. 6) Simplify the following functions, and implement them with two-level NOR gate circuits: F (u, z, y, z) = (0, 3, 12, 15) F (z, y, z) = (z + y) (z,+ z)]
