`I_(CM)` is the moment of inertia of a circular disc about an axis (CM) passing through its centre and perpendicular to the plane of disc. `I_(AB)`. is it's moment of inertia about an axis AB perpendicular to plane and parallel to axis CM at a distance `2/3 R`. from centre. Where R is the radius of the disc. The ratio of `I_(AB)` and `I_(CM)` is `x : 9` . The value of x is ––––––.
