Answer 4

@dip:
It's more important for the folks to learn than to just know what the answer is to a specific question.

Otherwise they won't know what to do on the test.

Answer 5

That's right!

Here's how you solve it now.

Keep in mind that you said 5 is in both 15 and 40.
Now... recall that a to the third means:
aaa

And a to the 1st means just
a


So... what letter do you see in both
a and aaa?

Answer 6

a:)

Bingo! And you know how to factor out the 5a from there?

Answer 8

Answer 9

Eh, I consider myself a computer geek, but I suppose. But I am in college, so that's probably why I'm a little faster than you expect. I've been doing this stuff for almost... 10 years now. Heehee.

Answer 10
