[8] Express the following function as a sum of minterms and as a product of maxterms : ?(?, ?, ?, ?) = ?̅? + ?̅? + ?? [9] Express the complement of the following functions in sum‐of‐minterms form : (a) ?(?, ? , ?, ?) = ∑(2, 4, 7, 10, 12, 14) (b) ?( ?, ?, ?) = ∏(3, 5, 7) [10] Convert each of the following to the other canonical form : (a) ?(?, ?, ?) = ∑(1, 3, 5) (b) ?(?, ?, ?, ?) = ∏(3, 5, 8, 11) [11] Convert each of the following expressions into sum of products and product of sums : (a) ? = (?? + ?)( ? + ?̅?) (b) ? = ?̅ + ?(? + ?̅)(? + ?̅) [12] Express the following functions as CSOP and CPOS expressions:
(a) F(x,y,z) = (x + y' + z)(x + z') + yz in terms of x, y, and z (b) F(w, x, y, z)=xy ̅̅̅(wz+w̅z̅ )(w+xz ̅ ) in terms of w, x, y, and z
