Question

free medal and fan.

x^-2 y^2/x^4 y^-3 x=4 and y=-2

Answer 1

Hi, can you help me with this?

Answer 2

What should we do? just solve?

Answer 3

Yes, evaluate the expression.

Answer 4

you just want the solution?

Answer 5

yes, explanation if possible.

Answer 6

Ugh, I also have another problem, The volume of a sphere is found using the formula V=4/3 3.14r^3. The area of a circle is found using the formula a=3.14r^2. What is the ratio of the volume to the area?

Answer 7

I got the ratio of the volume and area question. Just need help on the original.

Answer 8

\[\large \frac{x^{-2} y^2}{x^4 y^{-3}}\]

Answer 9

first thing to do is rewrite it as
\[\large \frac{y^5}{x^6}\]

Answer 10

correct, x=4 and y=-2

Answer 11

then go ahead and put in \(x=4,y=-2\) and get
\[\frac{(-2)^5}{4^6}\]

Answer 12

i believe the "final answer" will be
\[\large -\frac{1}{128}\]

Answer 13

Ok, thank you so much! I was trying to do the math. I got the same answer.

Answer 14

wait,what?
