I do not think this is hard but I am stuck on this. Please help me find an overall minimum two-level circuit

Problem 8: (6 pts): Find an overall minimum two-level circuit (corresponding to sum of products expressions) using multiple AND and one multi-input OR gate per function for the following set of functions. Show a K-map for each function, and draw the final two-level circuit. You will have to share terms between F and G to find the minimum circuit. F(a, b, c, d)-m(0, 1,2,3,6,7,8, 10, 13) G(a, b, c, d)-m(0, 1,2, 3, 8, 9, 10, 13)
