Detail solution
  1. Differentiate x5+5x\frac{x}{5} + \frac{5}{x} term by term:

    1. The derivative of a constant times a function is the constant times the derivative of the function.

      1. Apply the power rule: xx goes to 11

      So, the result is: 15\frac{1}{5}

    2. The derivative of a constant times a function is the constant times the derivative of the function.

      1. Apply the power rule: 1x\frac{1}{x} goes to 1x2- \frac{1}{x^{2}}

      So, the result is: 5x2- \frac{5}{x^{2}}

    The result is: 155x2\frac{1}{5} - \frac{5}{x^{2}}


The answer is:

155x2\frac{1}{5} - \frac{5}{x^{2}}
