    I am doing my revision on logic gates and I have a question.

    1. Use demorgans theorem to reduce this equation use only or gates. You cannot use the xor function in your equation.


    Here is my answer, I just need some clarification.



    then using demorgans


    = /(a+c)+(/a+/b)

    Firstly, how have you come about this step?

    I am also not sure you have applied DeMorgan's correctly, but we can deal with that later.
