### Problem 170

By making use of this way
I find out that
9*1087345 = 9786105
9*26 = 234

concatenated product for 9786105234 is the largest case that I could ever get up with.
In this question, is my understanding of style correct enough
or that am I missing off with something from this question
that is being unknown enough to me, as for now?

By the way, is this juxtaposition style for 9786105 along with 234
as above being a valid enough one, anyway, however man?

### Re: Problem 170

Is this atleast valid enough man?
18*547=9846
18*20639=371502

Thus its concatenated product being 9846371502
or are they otherwise being already
solely limited up to single digits only actually?

That is a valid solution. (just not the largest)

78*12645=986310
78*093=7254
So is 9863107254 a valid answer?

Solved the problem, and the answer to leading zeroes appears to be No.
