Detail solution
-
Apply the power rule: goes to
-
Now simplify:
The answer is:
The first derivative
[src]
n - 1
x *(n - 1)
--------------
x
$$\frac{x^{n - 1} \left(n - 1\right)}{x}$$
The second derivative
[src]
-1 + n
x *(-1 + n)*(-2 + n)
-------------------------
2
x
$$\frac{x^{n - 1} \left(n - 2\right) \left(n - 1\right)}{x^{2}}$$
The third derivative
[src]
-1 + n / 2 \
x *(-1 + n)*\5 + (-1 + n) - 3*n/
--------------------------------------
3
x
$$\frac{x^{n - 1} \left(n - 1\right) \left(- 3 n + \left(n - 1\right)^{2} + 5\right)}{x^{3}}$$
