Questions:

What is the remainder when 7^(2010) is divided by 13.

Number 13, 16, 27 on the district two test, how do you do those again? (sorry I should've written them down.)

Is there any way to quickly find the factors of a number?

Thanks in advance:)

Yeah. To be totally honest, I have no clue on what you did with the mod things. I got the other things down though, thanks.
I have a few more questions
From the 2010 SAC test:
15. Les Moor has a barrel of a 10% salt solution and a barrel of 25% salt solution. How many gallons of the 25% salt solution will he have to mix with some of the 10% solution to make six gallons of 15% salt solution.

Numbers 19 and 20.

Thanks:)

15. Assume for simplicity's sake that the percentages are by volume. The situation is governed by two equations: one for the total volume and one for the proportion of salt. If we let A and B be the amounts taken from the 10% and 25% barrels, respectively,

A+B=6

0.1A+0.25B= 0.15(A+B)=0.9
