 Homework Statement:
 The first image is the question, and the second is the hint.
 Relevant Equations:

ω=sqrt(g/L)
I=1/3ML^2 ?
The hint says to use the moment of inertia of the rod, however i have not covered this on my course and I don't know what it is.
After googling moment of inertia of a rod I found that it is a quantity expressing a body's tendency to resist angular acceleration, and for a rod I=1/3ML^2.
So ω=sqrt(g/L) and the hint says ω=sqrt(2mgd/I), so how is 1/L=2md/I?
