Best ResponseYou've already chosen the best response.0So is it done by just trying out numbers to show that it has to be greater than 6?

Best ResponseYou've already chosen the best response.1Sortof, it's finding the least power of 2 that is 1 more than a multiple of 9. That shows that one number is at least that many powers of 2 greater than the other, so they can't possibly have the same number of digits.
