# Math Help - Simple integration

1. ## Simple integration

Hiya,

The question I'm stuck on is:

Find the integral.

2/3x^4 dx

Could anyone help me with a step by step solution? Thanks!

2. $\frac{2}{3}x^{-4}$ will integrate to some fraction of

$\frac{2}{3}x^{-3} + c$ ... what fraction, though?

If you meant

$\frac{2}{3}x^{4}$ then some fraction of

$\frac{2}{3}x^{5} + c$ ... what fraction, though?

3. Sorry I meant

2/(3x^4) dx

4. Yeah, that's the first one above...

$\frac{2}{3x^4} = \frac{2}{3}\ \frac{1}{x^4} = \frac{2}{3}x^{-4}$
