Write it step by step:
1%2F5%283%2Aln%28x%2B1%29+%2B+2%2Aln%28x-1%29+-+ln%287%29%29 = 1%2F5%28ln%28%28x%2B1%29%5E3%29+%2B+ln%28%28x-1%29%5E2%29+-+ln%287%29%29 = 1%2F5ln%28%28%28x%2B1%29%5E3%2A%28x-1%29%5E2%29%2F7%29 = ln%28%28%28%28x%2B1%29%5E3%2A%28x-1%29%5E2%29%2F7%29%5E%281%2F5%29%29

And one important note: when you operate with the logarithm, use ln as the symbol (not In).
