    Limit x->infinity

    So this is a diffrent that i got no clue what to do next because i it got highest Power on top not dominator (on bottom on divide)
    limit x->infinity x^4+x^5 so i multi by (x^4-x^5)/(x^4-x^5) after some simplifie i get (x^8-x^10)/(X^4-x^5) and now i shall divide both with x^5 and at bottom i get -1 and at top im kinda confused


    edit:it is suposed to be x^(10) im having truble to get that 0 to top for some reason its not x^(1)0
