how to find the limit when x approaches zero?

I am completely stuck on this problem. I'm not sure if I'm suppose to use the conjugate or something else. If you could provide a step-by-step for the following so I understand it that would be helpful:

All of this is in one set of parentheses, first 1/t*Square Root(1 + t) this subtracted by 1/t

    You mean t->0?

    Then we have some formulate and methods to use in Limits.

    By direct substitution if we get,

    (i) 0/0 form,Use L-Hospital's rule (Differentiating numerator and denominator separately)

    (ii) Infinity - Infinity form, take LCM and solve

    I think for your problem,the second method is used.
