Discrete math Give a recursive definition of the set of bit strings whose length is an even number. For example, the length of the bitstring 0010 is 4, i. e. even, thus it belongs to the set. The length of bitstring 110 is 3, i. e. odd, thus it does not belong to the set.

Divide. write in the simplest form. 4 1/6 divided by 10
