Math question best answer will be given?

Question

question: ((a^(-10))-b^(-2))/((a^10)-b^2) simplify if possible best answer will be give to correct answer if answered by 4:57 pm eastern time september 5 2008.

P.S. magic robot ur answer to my last question was correct and i'll be choosing u as best answer as soon as possible.

Answer 1

Looks simplified

edit: guess I should have tried harder to work it out

Answer 2

((a^(-10))-b^(-2))/((a^10)-b^2) =

[(b^2-a^10)/a^10b^2]/(a^10-b^2)=

[-(a^10-b^2)/a^10b^2] * 1/(a^10-b^2) =

-1/(a^10b^2)

p.s.

you are now 5:00 pm?

I have the 10:32 pm!

to the next.

Answer 3

((a^(-10))-b^(-2))/((a^10)-b^2)= [(b^2-a^10)/b^2*a^10] / (a^10-b^2)=

-1/ (b^2*a^10)
