Question

What is 2xy/y^4 and (-x(y^4))/y^4?

Answer 1

\[2xy/y^4\] and \[-xy^4/y^4\] to be clear.

Answer 2

what do u want to do with them? solve them simultaneously or differentiate them implicitly

Answer 3

?

Answer 4

generally they are implicit functions... and you can do many things with them even derive a differential equation...

Answer 5

Sorry, for the late reply. I just want to divide them. I'm pretty bad when it comes to this. What do you get when you divide 2xy by y^4 and similarly for the second one?

Answer 6

\[2xy/y^4 \div (-x(y^4))/y^4\]

Answer 7

\[2xy /y^4= 2x/y^3\]

Answer 8

Ok, so would the first one be \[2xy/y^4 = 2xy^-3\] ?

Answer 9

\[\frac{2xy}{y^4}= \frac{2x}{y^3}\]

Answer 10

what happened is

Answer 11

Cool, same thing then. I'm pretty sure I get it. Thanks!

Answer 12

when u divide u subtract the power

Answer 13

when u multiply u add the powers

Answer 14

Got it. I just wasn't certain if the x was affected in any way. Thanks again.
