[tex] x^{8} *y^{3} [/tex] can only be written as [tex] x^{8}* y^{3} [/tex] or as [tex] x^{8} y^{3} [/tex]. One has the multiplication sign the other does not, which is why we put it together, because we know that if they are together they will be multiplied.
I hope this helps, if you have any other question on this or any other question, just ask. I am here to help.
