Answer 2

youre right, i could also cross multiply them to start right?

Answer 3

Yes. You Could. You Wanna Do It That Way?

Answer 4

Yeah, i've gotten 70xz-4x^2y^2 so far

Answer 5

Yup. That's Right.

Answer 6

And Being That None Of The Variables Are Alike, You Are Done.

Answer 7

Alright thank you, can you also help me with this one? : 2logx+logy-3logz i need to put it in simplified form

Answer 8

Sure.

Answer 9

I need to get the variables alone first right?

Answer 10

You Got It.

Answer 11

would it be something like: 2log+log/-3log? Im really lost with this one

Answer 12

So Log Is Basically Another Variable. Since Each Term Has The Variable Log, You Can Cancel Them All Out. So You'd Have Log X^2 (Because Of The Two On The Outside) , Y, And Z^3

Answer 13

And Being That Z^3 Is Negative (Remember The Sign Sticks) You Know What To Do To Get It Positive?

Answer 14

so z becomes z^3 once we get rid of the log? since it was 3logz before

Answer 15

Exactly.

Answer 16

Don't Forget About The - Though.

Answer 17

oh :o thank you

Answer 18

Welcome!
