    L = lim (1/(ax + 1))^(1/(bx))

    .....x-> 0

    lnL = lim ln((1/(ax + 1))^(1/(bx)))

    ........x-> 0

    lnL = lim ln(1/(ax + 1))/(bx)...now use L'Hopital's rule

    ........x-> 0

    lnL = lim (a/(ax + 1))/b

    ........x-> 0

    lnL = lim a/(abx + b)

    ........x-> 0

    lnL = a/b

    e^(lnL) = e^(a/b)

    L = e^(a/b)
