-5x^-13y/-8x^-4y simplify @Luigi0210

OpenStudy (luigi0210):

Let's see your attempt~

OpenStudy (anonymous):

\[-5x ^{-13y}\div8x ^{-4y}\]

OpenStudy (anonymous):

i really dont know how to start it

OpenStudy (luigi0210):

It's just trying to throw you off by adding in variables.. if they're the same variables then you add/subtract them like normal numbers, and the constants are just constants

OpenStudy (anonymous):

so would i subract the exponents?

OpenStudy (anonymous):

@Luigi0210

OpenStudy (luigi0210):

Yup, just subtract them, and what do you et?

OpenStudy (luigi0210):

*get

OpenStudy (anonymous):

-5x/8x^-9y

OpenStudy (anonymous):

well not the negative nine, positive. lol my bad

OpenStudy (luigi0210):

And that would be right :) And btw, are there two negative signs on the outside or just one?

OpenStudy (anonymous):

so would that be the answer? and what haha

OpenStudy (luigi0210):

And on your original ask question, it says "-5x^-13y/-8x^-4y"

OpenStudy (anonymous):

negative sorry lol

OpenStudy (anonymous):

the 8 should be negative

OpenStudy (anonymous):

so is the anwser 5x/8x^-9y @Luigi0210

OpenStudy (luigi0210):

If it's just the 8 that's negative, then it would be \(\Huge -\frac{5}{8x^{9y}}\) Btw, since it's the x that's holding the power, it follows the exponent. Sorry, forgot to mention that earlier
