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

1) 4/vy^2 + 9/vy^2

2) 13/vy^2
3) That's it.

Reading more carefully,

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

To add and simplify the expression 4/vy^2 + 9/yv^2, we need a common denominator.

The denominators in this case are vy^2 and yv^2. To find a common denominator, we can first write them both in the same order. Let's rewrite vy^2 as yv^2:

4/vy^2 + 9/yv^2

Now that we have the same denominators, we can combine the fractions:

(4yv^2 + 9yv^2) / (yv^2 * yv^2)

Simplifying the numerator:

(4yv^2 + 9yv^2) = 13yv^2

The expression becomes:

13yv^2 / (yv^2 * yv^2)

Now, let's simplify further by canceling out common factors:

The yv^2 terms in the numerator and denominator cancels out, leaving us with:

13 / yv^2

So, the simplified form of 4/vy^2 + 9/yv^2 is 13 / yv^2.
