I'll help you see where this comes from.
f has units 1/[T].
f-dot has units 1/[T]^2, because it's the time derivative of the frequency.
So the product inside the brackets has units [T] to the 11/3 power 
divided by [T]^2. So that power is 11/3 - 6/3 = 5/3.
Now you take that quantity to the 3/5 power, leaving you with [T] to the 
(5/3) x (3/5) power or just [T].

It's not difficult.
