What is the cross product of the cross product of the dot product of the vectors a = <3,4,5> and b = <5, 6, 7>?
What does it geometrically mean?

you cannot find the cross product of the dot product of two vectors.
The dot product of two vectors results in a scalar, and the cross product is an operation formed on two vectors, so you need two VECTORS as inputs.
Your question does not make sense.

Lets say you have two vector a and b. Take the dot product
a . b = s where s = scalar. Now the cross product of a scalar with a vector is undefined - cross products are only defined among vectors. So I don't understand the question. Perhaps you phrased it incorrectly?

Well, when you do the dot product of two vectors, you get a scalar, and when you do the cross product of two vectors, you get a vector back. In your case though, it's not possible, since you can't do a cross product of scalars because that's not defined.
