$$\\\frac{2X^{-3}Y^2*(2Y)^{-2}}{2X^{-4}Y^2}\\\\
=\frac{\not{2}X^{(-3--4)}Y^2*2^{-2}Y^{(-2-2)}}{\not{2}}\\\\
=\frac{X^{1}Y^2*2^{-2}Y^{-4}}{1}\\\\
=\frac{X^{1}*2^{-2}Y^{(2-4)}}{1}\\\\
=\frac{X*2^{(-2)}Y^{(-2)}}{1}\\\\
=\frac{X}{1*2^{(+2)}Y^{(+2)}}\\\\
=\frac{X}{4Y^{2}}\\\\$$

Thanks Brodudedoodebrodude      and welcome to the forum :)

Maybe another mathematician would like to give this one a shot?

You are not dumb, I didn't answer it because it was hard and i was short of time.

Maybe I could not have answered it.     

Maybe if you play around with part A and really underfstand it, you will be able to figure out part b just as easily as I could.   

I will see if time allows me to look at it more.  

I think a formula for an odd number of sides shouldn't be too hard to develope from what i have done but maybe it is different for an even number of sides.   

I put that first line there to try and attract others to take a look.  

Interesting pics Mellie, thanks    

Zegroes  -   dream on!

I am heading for bed.  Good night all :))

Poor Zegroes, I gave you some points because I feel sad for you, poor Zegroes  :((((

Rosala, you can eat and enjoy that cake with impunity!

It is a magical cake from the magical kingdom of Camelot.

*From it I can take an infinite number of slices.

*It never goes stale and always tastes and looks delicious.

*It has absolutly no calories.  You can eat a million slices and you will never feel bloated.

*So Rosala, you can and should eat as much as you want and it will not break your diet  :)))

cubed zegroes      cubed !!!

6 cubed is 6^3   or    6³       

and it means      6*6*6 = 216

Thanks Nauseated.     

Did you enjoy the icecream?
