Question

(2x^-2+y^-2) divide by (x^-1-y^-1) simplify complex fraction.

Answer 1

Okay..

Answer 2

???

Answer 3

one second. these get messy.

Answer 4

Okay so basically this is what you do, step by step?

Answer 5

i figured

Answer 6

watch.

Answer 7

okay

Answer 8

so according to your exponent laws, any variable divided by another variable is a subtraction of exponents. so x^2 divided by 2 is x^2-1, so x.

Answer 9

Negative exponents make them become the denominator. the fraction is flipped.

Answer 10

yup

Answer 11

So what you have to do is separate it to 2x^-2 divided by x^-1 -y^-1 +y^-2 divided by x^-1 -y^-1

Answer 12

then you flip.

Answer 13

once all the fractions are flipped, you get positive exponents.

Answer 14

can u show me how would it actually look

Answer 15

you can then simplify, remember your exponent laws!

Answer 16

right

Answer 17

so this is what you get once you flip them:

Answer 18

By the way, forget that separation of fractions thing, you won’t need that yet

Answer 19

just take your old equation, the first one

Answer 20

flip it. You will get:

Answer 21

x\[x^1 - y^1 /2x^2\]

Answer 22

i thin thats wrong

Answer 23

answer is 2y^2+x^2/ xy(y-x)
