(7/w)+(8/w^2)
2 answers
place each of them on a common denominator of w^2, so it will become (49/w^2) + (8/w^2) = (57/w^2)
Jordan, that is a major error
You don't "square" a fraction in the process of finding a common denominator.
(7/w)+(8/w^2)
= 7w/w^2 + 8/w^2
= (7w+8)/w^2

(7/w)+(8/w^2)
= 7w/w^2 + 8/w^2
= (7w+8)/w^2
