Question 6142
the difference of logs with the same base can be expressed as a fraction:
1.  {{{log3(u^2/v)}}}
The sum of logs with the same base can be expressed as multiplication:
2. {{{log2(1/x^3)}}}
This is a complex fraction, so you have to flip and multiply:
3. {{{log(((x^2+2x-3)(x+2))/((x^2-4)(x^2+7x+6))))}}}
