What have you tried? Might I suggest U = something? Give it a go. Let's see your best result.
Maybe separate the square root argument into two fractions and then factor out a nice even exponent piece and perhaps something will present itself.

Do you see:
\(\displaystyle \sqrt{\frac{x^3-3}{x^{11}}} \ = \ \frac{1}{x^4} * \sqrt {1 - \frac{3}{x^3}}\)
What can you do(have you done) with that information towards solving this problem?
