bascially i need to prove the above equation with boolean algebra


if you don't want to do the whole thing for me, some explanations are good too

 

Can you define what the variables represent. Since there appear to be three outputs labeled Q0, Q1 and Q2, and a single input labeled D1 I'm having a bit of trouble seeing what exactly you are trying to prove.
