Question

8x^-1+5y^-1/-3x^-2_9y^-2= simplify complex fraction

Answer 1

What's the underline representing?

Answer 2

Did you miss out any parentheses?

Answer 3

-3x^-2- 9y^-2

Answer 4

Underline was a negative

Answer 5

Okay, but did you miss out any parentheses?

Answer 6

No that is t math problem

Answer 7

That means is it \(\displaystyle\frac{8x^{-1}+5y^{-1}}{-3x^{-2}-9y^{-2}}\) or \(\displaystyle8x^{-1}+\frac{5y^{-1}}{-3x^{-2}}-9y^{-2}\)?

Answer 8

The first one

Answer 9

That means you've missed out two pairs of parentheses.

Answer 10

Convert all the terms with negative indices into fraction first, i.e. 8x^(-1) => 8/x & etc

Answer 11

You should have \(\displaystyle\frac{\frac8x+\frac5y}{-\frac3{x^2}-\frac9{y^2}}\)

Answer 12

Okay then multiply the whole thing by xtwo and ytwo

Answer 13

Yep you can do so, what do you get after doing so?

Answer 14

Draw it out or use equation editor, as your preference

Answer 15

8xy^2+5x^2+y/3y^2-9x^2 drawing doesn't work well with my tablet but this is the solution I have on the answer key

Answer 16

Then you can just use plain text, but remember to put parentheses into appropriate position Oh God

Answer 17
