Add. Simplify if possible. 4/vy^2+9/yv^2

To add the fractions 4/vy^2 and 9/yv^2, you need to find a common denominator. Looking at the denominators, we have vy^2 and yv^2.

To simplify the expression, we can notice that the denominators have the same terms, just rearranged. Therefore, we can rewrite the expression as:

4/(vy^2) + 9/(yv^2) = 4/(vy^2) + 9/(vy^2)

Now that we have the same denominator, we can combine the numerators:

= (4 + 9)/(vy^2)

= 13/(vy^2)

Thus, the simplified expression is 13/(vy^2).
