Q13:

For any positive integer x, the 2-height of x is defined to be the greatest nonnegative integer n such that 2ⁿ is a factor of x.  If k and m are positive integers, is the 2-height of k greater than the 2-height of m ?

(2)     k/m  is an even integer.

How to do this question and what is 2-height?

Thanks a lot
