lol...omg i'm still lost...
is this the next step, i dont understand how you get it to equal to an integer...i.e. get rid of the beta

Quick Question for this expression: how do u get rid of the to make it equal to 5? i understand that it will be equal to 5 is it that i dont have to worry about the theta and jus simplify it equal to five i.e.
