An example of this is:

a^3b-2/3^-1a^4b^-3

(-3x^-2y^3/3^-3x^4y^8)^-2

Sorry if these two examples look messy I don't know how to write it out like people write equations on this site.

a^3 b^-2 / (3^-1 a^4 b^-3)

for the first one.

Thanks for the tip Hurkyl. Do you have any ideas on how to solve them?

[tex]x^{a}x^{b}=x^{a+b}[/tex] and [tex]\frac{x^{a}}{x^{b}}=x^{a-b}[/tex].

And, of course, [tex]x^{a}y^{b}\neq xy^{a+b}[/tex] and the same for the fractions.

Hint: If you click on the LaTeX images above you can see the code and learn how to use it in this forum.

But if you have a solution to the above problems it would definitely give me a kick start to my homework.

[tex]\frac{a^{3}b^{-2}} {3^{-1}a^{4}b^{-3}}[/tex]

[tex]=3a^{-1}b[/tex]

[tex]=\frac{3b} {a}[/tex]

if you cant see th LaTeX, I probobly put it in wrong, here's my work in plain text:

(a^3 b^-2) / (3^-1 a^4 b^-3)

= 3a^-1 b

=(3b) / a

That looks correct. And yes, I can see the LaTeX.

Well I've looked at a few math help sites and a few tutorials, got some help from a teacher today, and didn't understand the lesson in calss yesterday, but I finally understand it :p

talk about dedication to the "arts" :)

I have a question that's written like this [tex]x^{2}y^{-3}[/tex] but I have no clue as to what they're asking of me.

Well I thank you for your assistance Assyrian, but I'm going to go watch Harry Potter and the Goblet of Fire now while I redue all of my homework.

Thanks again, bye.
