Why not differentiate the function you have been given? That would be appropriate since a differential equation is an equation that has derivatives in it...

how to find the derivatives of this

Take a Calculus course! Then you will learn that the derivative of is simply , that the derivative of is for all n except n= 1, and the "product rule": the derivative of f(x)g(x) is the derivative of f(x) times g(x) plus f(x) times the derivative of g(x)- (fg)'= f'g+ fg'.

y= f(x) satisfies the DE y'=f'(x). For ex, if y=x^2, the DE is dy/dx = 2x.

That's the crux of the question. The actual differentiatin should be trivial.
