Hello,
some one can help me please and explain to me how to prove this:
$\displaystyle
(A\cap B)\cup(A\cap B\cap \overline{C} \cap D)\cup(\overline{A} \cap B) = B
$
Thank you very much!
I ready don't know to go to it...

You should understand that this is not a homework service nor is it a tutorial service. We help people who already have a basic grasp of the material.
You posted the question. Therefore, you should know what the symbols mean. Frankly, I do not know what $\displaystyle \overline{C}$ means in this context. I guess it probably means the set complement.
That is why you have text material. The identity is still correct.
For every set $\displaystyle X$ it is the case that $\displaystyle X\cap P\subseteq P$. It is true $\displaystyle (A\cap B)\cup (\overline{A}\cap B)=B$.
