Are you in Year 9 only?

\int \frac {ln ([3x^5 + 3]^{5x^4})}{x^5 + 1}dx \\ \\ = \int \frac {5x^4[ln(x^5 + 1) + ln 3]}{x^5 + 1}dx \\ \\ = \int ln(x^5 + 1)\cdot \frac {5x^4}{x^5 + 1} dx + ln 3\int \frac {5x^4}{x^5 + 1} dx \\ \\ = \int ln(x^5 + 1)dln(x^5 + 1) + ln3\int \frac {1}{x^5 + 1}d(x^5 + 1) \\ \\ = \frac...
