Answer:

The answer is
y^(') =e^{(1)/(x) } (2x-1)

Explanation:

First of all, we have product of 2 functions
e^(1/x) and
x^(2)


y^(') =u(dv)/(dx)+v(du)/(dx)

Let
u=e^(1/x) and
v=x^(2)

using chain rule for
u,
(du)/(dx)=-(1)/(x^2)

and
(dv)/(dx)=2x

Therefore,


y^(') =u(dv)/(dx)+v(du)/(dx)=e^(1/x)(2x)+x^(2) (-(1)/(x^2))=e^(1/x)(2x-1)
