which expression is equivalent to sqrt 8/x^6. assume x > 0

We have the following expression:
 sqrt 8 / x ^ 6
 Rewriting we have:
 sqrt (8 / x ^ 6)
 sqrt (2 * 4 / ((x ^ 2) * (x ^ 2) * (x ^ 2)))
 (2 / (x * x * x)) sqrt (2)
 (2 / x ^ 3) * sqrt (2)
 Answer:
 An equivalent expression is given by:
 (2 / x ^ 3) * sqrt (2)
