Find the second derivative of the equations: Chain rule?

Question

65. y= (e^x^2) +5x

61. y=(1+(1/x))^3

Answer 1

65).

Apply derivative each side.

Derivative of Exponential Functions:

                                        [inner derivative of x² = 2x]

Again apply derivative each side.

The Product Rule: (UV)'=UV'+U'V

Answer 2

y=(1+(1/x))^3

Mathematics formulas: (a+b)³= a³+3a²b+3ab²+b³ and 1/a = a^-1

Apply derivative each side.

Power Rule of Derivative

Again apply derivative each side.
