Hi Folks

Need to solve this (A+B)(A+B) by using de morgans theorem. I reckon the naswer is A exor B but when i try to solve it I can't work it out, Any ideas would be greatly appreciated.

Is something missing?
(A+B)(A+B)=A+B.
Not sure how you would use DeMorgan's theorem to prove this, or why you would want to.
