Which of the following is an incorrect SOP expression?(a) x+x.y(b) (x+

1.	Which of the following is an incorrect SOP expression?(a) x+x.y(b) (x+y)(x+z)(c) x(d) x+yThe question was asked in quiz.This interesting question is from SOP & POS in section Boolean Algebra and Logic Circuits of Computer Fundamentals
Answer» The correct answer is (b) (x+y)(x+z) For EXPLANATION I WOULD say: The second expression is incorrect because it consists of TWO maxterms ANDed together. This MAKES it a POS or the product of SUM expression. Other options are valid SOP expressions.
