Using Karnaugh map to find the logic function f (a, B, C, d) = ∑ m (1,4,9,13) + ∑ D (5,6,7,11,15) Karnaugh map and simplification process, urgent

Using Karnaugh map to find the logic function f (a, B, C, d) = ∑ m (1,4,9,13) + ∑ D (5,6,7,11,15) Karnaugh map and simplification process, urgent

F(A,B,C,D)=∑m(1,4,9,13)+∑d(5,6,7,11,15)
=[∑m(4)+∑d(5,6,7)]+[∑m(1,9,13)+∑d(5)]
=C'D+A'B
