Given -5ln%287%29-2ln%28x%29%2B4ln%28x%5E2%2B7%29, use the rule log%28b%2CA%5Ec%29=c%2Alog%28b%2CA%29. Apply that rule to every term in your given expression.

First step gives you ln%287%5E%28-5%29%29%2Bln%28x%5E%28-2%29%29%2Bln%28%28x%5E2%2B7%29%5E4%29.
Not sure where you want to head with this, but a next step might be to combine as ln%287%5E%28-5%29x%5E%28-2%29%28x%5E2%2B7%29%5E4%29, or better,
highlight%28ln%28%28x%5E2%2B7%29%5E4%2F%287%5E5%2Ax%5E2%29%29%29.
