My cat has fleas, do I need to treat my carpet too?

I have a beautiful tortoise shell calico. I was brushing her tonight and noticed she had a lot of flea dirt. I thought it was odd since, as far as I knew, she didn't have fleas. I combed more and more and found more and more. Finally I started combing her hair apart to check if she did have fleas and saw one move. I parted some more hair just to make sure and I found another one, or could have been the same one I don't know. A couple years ago we had fleas pretty bad on all our animals. At the time it was 4 cats, 2 ferrets and 2 dogs and our main concern was the ferrets since they can die from anemia from flea bites. We used some flea spray for the vet and it really helped. There were no more fleas on the ferrets and we didn't find any on the cats either. Last night was the first time I have seen one since that time. Two of my cats are much easier to check because they are lighter colored so you can see fleas move through the fur. None of them have shown signs of extra itchiness.

(a^m − 1, a^n − 1) = a^(m,n) − 1.?

Let m, n be positive integers and let a be an integer greater than 1. Show that (a^m − 1, a^n − 1) = a^(m,n) − 1.

How would I grind through it? Couldn't I use m>n with m=qn+r and then...

use GCD / Euclid's Algorithm.. and then..again..then..
