Problem Statement: Using Boolean Algebra, determine whether or not the following expressions are valid: I don't even know how to start questions like this. I'm not too bad in boolean algebra however when I'm doing a questions as complicated as this it's overwhelming. I can't formulate an attack plan with an equivalent of this complexity, I feel like I just have to start adding terms that are equivalent to 0 and try to reduce to the RHS somehow. How can I plan out my attack so that I have more of a chance of turning the LHS into the RHS? What specific characteristics or hints do you look for? Thanks again!
