22 (2-2-y) and 2y (2-y-u).​

Answer 1

Step-by-step explanation:

It all works out, using (22):. ∂(u, v). ∣. 2x. −2y ∣. 2. ∂(x, y). 1. ∂(x, y). = −y/x2. 1/x= 2 − 2y 2/x2 = 2 − 2v ; so. ∂(u, v). = 2(1 − v2).

Answer 2

Answer:

${ \frac{ {39 \times \frac{73}{4673} }^{2} \times \frac{67}{497} }{74} }^{76} \times \frac{34}{767}$
