    Hi

    I need help, not only for solving these boolean algebra problems but also to explain the solution :(


    -Which if any of the following are valid Boolean expressions? What is wrong with those that are not?

    a. (A.B) + (A’.C)

    b. A + B . (C + D(.E’ + F’))

    c. X1 . X2 = (X1/X2)’

    d. 1 . (0 + 1. (0 + A)’)


    :confused:

    Equation c is not a valid bolean expression because boolean algebra does not use the / operation.

    Equation b is not a valid boolean expression becaue of one syntax error. The "." should be outside the parenthesis. A+B.(C+D.(E'+F')

    A valid expresion follows the proper syntax of boolean expressions.
