Integral of 9*x^8 dx

The solution

You have entered [src]

$$\int\limits_{0}^{1} 9 x^{8}\, dx$$

Integral(9*x^8, (x, 0, 1))

Detail solution

The integral of a constant times a function is the constant times the integral of the function:

$\int 9 x^{8}\, dx = 9 \int x^{8}\, dx$
1. The integral of $x^{n}$ is $\frac{x^{n + 1}}{n + 1}$ when $n \neq -1$ :
  
  $\int x^{8}\, dx = \frac{x^{9}}{9}$
So, the result is: $x^{9}$
Add the constant of integration:

$x^{9}+ \mathrm{constant}$

The answer is:

$x^{9}+ \mathrm{constant}$
