Were asked to add and simplify and we have the principle root of two x squared plus four times the principle root of eight plus three times the principle root two x squared plus the principle root of eight so we can do a little bit of adding we can actually simplify first and then add or we can add first and then simplify but it looks like we can already add so lets try and do that so here right over here I have a principle root of two x squared and.
