For each implicant in F, indicate its reducibility.Perform the Expand operation on F(a, b, c) = E(0, 1, 2, 5, 6, 7) where E = summation, to get a cover C using the following rule: expand the minterms in the order as they appear in F, and visit the variables in the order [c, a, b]. Give the answer in equation form, e.g. C = a * b + c?
