## anonymous 5 years ago (8m^3n^2)/(4mn^3)

simplyfy assume that no vaiable equals 0

Refer to your rules for exponents 2m^2n^-1 or 2m^2/n

$2m ^{2}n ^{-1}$ or (sometimes preferred)$2m ^{2}/n$

i dont understand. my algebra 1 class which was the basics of this i didnt get to take because the teacher was lazy then this year we just went back to review it and i didnt understand a bit of it

5. anonymous

$\frac{8m^3n^2}{4mn^3} = \frac{8*m*m*m*n*n}{4*m*n*n*n} = \frac{8}{4}*\frac{m*m*m}{m}*\frac{n*n}{n*n*n}$

6. anonymous

now just cancel stuff.

Rules for multiplying terms with exponents are pretty few and simple. First the base has to be the same such as x or y etc. if you are multiplying like $x ^{3}\times x ^{2}=x ^{5}$

If dividing subtract

You can also make this a bit less tedious by using: $\frac{8m^3n^2}{4mn^3} = \frac{8*m*m^2*n^2}{4*m*n*n^2}$

10. anonymous

Then cancel stuff that has the same power. But eventually you'll realize that you're just subtracting the exponents on the bottom from the exponents on the top (or adding negative exponents).

Polpak, how do you get that line in your fractions (the long line??

12. anonymous

good question i wish i knew it would make typing the equations out alot easier

13. anonymous

Well I don't use the equation editor cause it causes issues so I type them all by hand. The syntax they use here is called latex, and for doing fractions you just have \frac{numerator}{denominator}

14. anonymous

im new to the whole program so i just make it look as close as i can

Let me try it: \frac{8345}{5432}

it didn't work for me!

17. anonymous

i worked the problem out and i got the answer as 8m^2n^-2

18. anonymous

no wait negitive 1 not ^-2

19. anonymous

No you have to put it in the equation format. All equations must be surrounded by \ [ \] (but no spaces betwen the \ and the [)

20. anonymous

$8m^2n^-1$

21. anonymous

It should be $\frac{2m^2}{n}$

22. anonymous

So you have it right for m and n, just forgot to divide the leading coefficients.

23. anonymous

ok

24. anonymous

Also when typing negative exponents in latex you have to use n^{-1}

25. anonymous

ok

26. anonymous

Did you figure it out radar?

Not yet don't want to slow down themudbug93 while he is on a roll

28. anonymous

Try (with no spaces): \ [ \frac{1234}{4321}\]

29. anonymous

haha radar i got it sorta figured out. i gotta go do some other things and ill be back on later tonight

$\frac{1234}{4321}$

31. anonymous

You got it npw =)

Thanks a lot.

33. anonymous

I fanned you but did not see it increment!

35. anonymous

Sometimes it takes a second to refresh. It looks like it worked though ;)

$\frac{8m^{3}n^{2}}{4mn^{3}}$ Eureka!!!
