    Because to find the limit of the two, you find the limit of each one individually (e^t) and (t^n). you can plug anything into n, like 5. the limit for\[e^\infty\] is infinity. (look at an e^x graph) and limit for \[\infty^5\] will be infinity

    \[\infty\] because an exponential function increases more rapidly than a function (?)

    sorry, bad at mathematical terminology; if you weren't in a rush I'd Google the right term for it. basically the (e^x) will grow faster than the (t^n) so the limit will be infinity

    this works to infinity though if n>0

    ya i dont think you can do this one otherwise than looking at the function's 'growth rates"

    infinity is not a limit so i guess there is no limit

    if you had like cos(pi*n) as n->infinity then you can say there is none because it keeps oscillating between -1 and 1
