 Hi and welcome to the session. I am Shashi and I am going to help you with the following question. Question is, find the second order derivatives of the functions. The given function is x raised to the power 20. Now, let us start the solution. First of all, let us assume y is equal to x raised to the power 20. Now, differentiating both sides with respect to x, we get dy upon dx is equal to 20, multiplied by x raised to the power 19. Now, again differentiating both sides with respect to x, we get d square y upon dx square is equal to 20, multiplied by 19, multiplied by x raised to the power 18. Now, the second order derivative of y is equal to 318 multiplied by x raised to the power 18. So, our required answer is 380 multiplied by x raised to the power 18. This completes the session. Hope you understood the session. Take care and goodbye.
