Simplify the Boolean expression (a + c) (~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 * b or a & b. OR: either + or . For example, a + b or a | b. NOT: either ~ or ! before the value it will affect. For example, ~a 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
