how the hell?!

- anonymous

I assume that is
\[\frac{2x-4}{5x}\frac{15x}{x-2} \]
right?

- anonymous

You can rewrite that like this...
\[\frac{2(x-2)}{5x}\frac{3(5x)}{x-2} \]
which would be six, no?

correct how did u write it like that? i cant write it like that in the question box

- anonymous

but i dont know how you are even re writing it

- anonymous

It's called LaTeX, don't worry about it. And just look at it, I dunno what else to tell you really. 2x-4 = 2(x-2), right?

- anonymous

yes

- anonymous

So, the (x-2)'s cancel, and the 5x's cancel, leaving you with 2*3 = 6.

- anonymous

ohhhhh okay thank you!

- anonymous

so what about -8 X n/-3msquared

- anonymous

you can cancel the negative signs.

- anonymous

this is such hard math

- anonymous

i dont know how to calculate algebraic functions

Such as?

i dont know to write it

(5/pqSQUARED) ( -3pCUBEDr/10q)

- anonymous

\[\frac{5}{pq^2}\frac{-3p^3r}{10q}\]
?

- anonymous

how do u do that?

- anonymous

You'll notice the "Equation" button just below the text box.

- anonymous

i see it but i havent figured out how to work it

- anonymous

It's a document typesetting language called LaTeX. If you can't work the buttons don't worry about it because what I just typed looks like this:
"\frac{5}{pq^2} \frac{-3p^3r}{10q} "

- anonymous

I understood what you meant well enough when you just typed it.

- anonymous

okie doke

- anonymous

And to answer your question, that would be
\[\frac{-15p^3r}{10pq^3} = \frac{-3p^2r}{2q^3}\]

- anonymous

can you explain how you got that?

- anonymous

I can tell you that when you multiply fractions, you multiply the numerators and denominators together, and that 15 and 10 share a common factor of 5 so that reduces to 3/2 when you cancel it, and p^3 / p = p^2, but besides that, I apologize, I do not know how to explain it further.

- anonymous

thanks i just not that good at math
