Question
If m and n, respectively, are the order and the degree of the differential equation `d/(dx) [((dy)/(dx))]^4` = 0, then m + n = ______.
Options
1
2
3
4
Solution
If m and n, respectively, are the order and the degree of the differential equation `d/(dx) [((dy)/(dx))]^4` = 0, then m + n = 3.
Explanation:
The given differential equation is `4 ((dy)/(dx))^3 (d^2y)/(dx^2)` = 0.
Here, m = 2 and n = 1
Hence, m + n = 3
