# Determine the order and degree of the following differential equation: dydxdydx(d3ydx3)2=1+dydx5 - Mathematics and Statistics

Sum

Determine the order and degree of the following differential equation:

(("d"^3"y")/"dx"^3)^2 = root(5)(1 + "dy"/"dx")

#### Solution

The given D.E. is

(("d"^3"y")/"dx"^3)^2 = root(5)(1 + "dy"/"dx")

(("d"^3"y")/"dx"^3)^(2xx5) = 1 + "dy"/"dx"

(("d"^3"y")/"dx"^3)^10 = 1 + "dy"/"dx"

This D.E. has highest order derivative ("d"^3"y")/"dx"^3 with power 10.

∴ the given D.E. is of order 3 and degree 10.
