Simplify the Boolean expression (a + c)(a + d) (a + ~c) Your answer must be written as a sum of products; use the fewest implicants possible; use the fewest literals possible within each implicant. Boolean algebra expressions can be written as follows: AND: either * or &. For example, a * bora & b. OR: either + or 1. For example, a + b or a b. NOT: either or ! before the value it will affect. For example, va or !a. Grouping with parentheses. For example,~(a + b) * c. True or False if the expression simplifies to a tautalogy or contradiction. intermediate step 1 (ungraded): intermediate step 2 (ungraded): intermediate step 3 (ungraded): simplified expression
