You can put this solution on YOUR website! How many 6 digit numbers can be made from 2 different digits (e.g. 3 and 7 = 333777, 373737 etc).
----------
Each of the 6 digits is 1 of 2 choices.
--> 2^6 = 64
===================
Using 2 digits is binary.
6 digits in binary has a range of from 0 to 63, = 64 numbers.
