Answer:

Step-by-step explanation:
We are given that DE

We have to determine given DE is exact or not.
Compare it with Mdx+Ndy=0





Therefore, 
If DE is exact then 
Hence,it is exact.

Integrate w.r.t x on both sides

...(1)
By using the formula

Differentiate partially equation (1) w.r.t y

By using the formula:




Integrate w.r.t y

Substitute the value
