Question

1/w+1/x divided by w^2-x^2 divided by wx

Answer 1

= (1/w+1/x ) / [(w^2-x^2) wx]
= (w+x) / [(wx)^2 (w+x)(w-x)]
= 1/ [(w-x)(wx)^2]
=1/ (w^3 x^2-w^2 x^3)

Answer 2

correct answer was 1/w-x

Answer 3

thnks for your hlp

Answer 4

wait does your question means (1/w+1/x )divided by (w^2-x^2 divided by wx) or (1/w+1/x divided by w^2-x^2 )divided by wx ?

Answer 5

i thought it was the 2nd choice

Answer 6

if it is the first one, then
= (1/w+1/x ) / [(w^2-x^2) /wx]
= (w+x) (wx) / [(wx) (w+x)(w-x)]
= 1/ (w-x)
