Calculus Help?

Hey gang! I'm totally confused on this calculus question and could use some help. I know that its an indeterminate power and requires use of l'Hopital's, but I'm stuck. The question is to find the limit of the following equation as x--> 0

y= (1-10x)^(1/x)

Thanks for your help!

    lim (x -> 0) (1-10x)^(1/x)

    = lim (x -> 0) (1 - 10x)^[ (-1/10x) * (-10) ]

    = e^(-10)

    By L hospital Rule

    =limx->0 -10/(-1/x^2)

    =lim x->0 10x^2

    =0

    From a common sense standpoint, I'd say that the limit is 1.

    Since 1-10x approaches 1 and 1/x approaches 0 and 1^0 = 1, thats my approach. Nothing fancy here.
