Question

If w, x, y, are Boolean variables, then which of the following is incorrect?

• A. wx+w(x + y) + x(x+y)=x+wy
• B. \(\overline{w\bar{x}(y+\bar{z})}+\bar{w}x=\bar{w}+x+\bar{y}z\)
• C. \((w\bar{x}(y+x\bar{z})+\bar{w}\bar{x})y=x\bar{y}\)
• D. (w+y)(wxy+ wyz) = wxy + wyz

Answer 1

The Correct Option is C

The correct answer is(C): \((w\bar{x}(y+x\bar{z})+\bar{w}\bar{x})y=x\bar{y}\)
