Using Karnaugh map simplify the following function, then implement it using NAND gates only.

2. Using Karnaugh map simplify the following function, then implement it using NAND gates only. a. RA,B,C,D) = Po P2 + P3 + P7 + P8 + P10 + Pii + P15 b. Represent the complement of the above function by its canonical product of sums (S form), simplify it, and then implement it using NOR gates only.
