I’m not sure exactly which expression you mean — could you confirm? Meanwhile, here’s the general connection and a likely example.
Rule: a^(m/n) = the n-th root of a^m = (n√a)^m.
Equivalently n√(a^m) = (n√a)^m = a^(m/n).
Example (if you meant 3^(2/5)):
3^(2/5) = 5th root of 3^2 = 5√(9) = (5√3)^2.
Note: if n is even you normally require a ≥ 0 for real-valued roots; if n is odd negative bases are allowed.
