Can I have help with b please.

Problem 4 (6 Points) Assume that we have two "black boxes", shown in Figure (a) and (b). Black box shown in Figure (a)takes two numbers as input and outputs their sum. Black box shown in Figure (b) takes two numbers as input, and multiplies them together. As an example, Figure (c) shows how we can connect these boxes together to compute p * (m + n) m nP m +n m *n p (m n) Show how to connect these boxes together to compute the following expressions (Note: Try to simplify the equation to express them with as few boxes as possible. Use only +, , m1 + n' *3'm'n*(n) (can be accomplished with 3 boxes) + n3 +3*m*n*(m + n) (can be accomplished with 3 boxes)
