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

    1. Differentiate x1x - 1 term by term:

      1. Apply the power rule: xx goes to 11

      2. The derivative of the constant 1-1 is zero.

      The result is: 11

    So, the result is: 12\frac{1}{2}

  2. Now simplify:

    12\frac{1}{2}


The answer is:

12\frac{1}{2}
