Math geeks only

I specified integer values only.

But to answer your question, yes. There is a non-integer value (that I'm ill equipped to work out at the moment) of n, between 2 and 3, for which n*7 = 10^(n-1). Below that value, the result is > 10^(n-1), above it, it's > 10^(n-1).

Ah, that would be me forgetting that integer meant a whole number

(Proof that I'm not a math geek... now ask me the integer value that represents how many times I had to take algebra II in order to pass it. Hint: n>2)

Just because this IS a number theory thread, I should point out that in most mathematic circles "whole numbers" consist of the positive integers (or the very similar "non negative integers" which also includes 0). So while whole numbers are indeed integers, an integer is not necessarily a whole number.

But in this particular case, we do happen to be dealing with only whole numbers.
