The order and degree of the differential equation (d4y/dx4)2 + (dy/dx)8 + 9y = log(x) is-
Answer & explanation
Correct answer: option 4
The order of the differential equation is the order of the highest derivative involve in the differential equation so the order of the differential equation
(d4y/dx4)2 + (dy/dx)8 + 9y = log(x) is 4.
The degree of the differential equation is equal to the power of the highest derivative involve in the equation so the degree of the given differential equation (d4y/dx4)2 + (dy/dx)8 + 9y = log(x) is 2.
