2. Apply "i(j+j') simplification to simplify the following expressions. Show your work (show the terms removed) and report the final, simplified result. Example: xyz + xyz = yz (x+x¹) = yz a. a'b' + ab' = ?? b. a'bc'd + a'bcd = ?? c. a'bc' + abc' = ?? d. (a+b)(c+d) + (a+b)'(c+d) = ?? e. a'bc'd + abcd = ??
