**1. The problem statement, all variables and given/known data and 3. The attempt at a solution**

Simplify the equation in the following picture using karnaugh.

I divided it into two cases, one I used the square and the other I used the 2×1. Will either method work to get the solution, or is the 2×2 better since it is more simplified?

Let’s say I wanted to simplify the case 2 solution to get case 1 without karnaugh, how would I got about doing this?
