The first two will combine logs into a single log, the first for when there is a "+" between the logs and the second for when there is a "-" between. These two properties require that the bases of the logs be the same and that the coefficients of the logs are 1's. The third property can be used to "move" a coefficient that is not 1 into the argument as its exponent.
Since none of the logs in your expression have a coefficient of 1, we will start by using the third property to move those coefficients into the argument as the exponent:
All those fractional exponents represent roots of various kinds. Since radicals display better on algebra.com I am going to rewrite all those roots in radical form before proceeding:
Now we can start using the other two properties to combine these logs. The first two have a "-" between them so we use the second property:
The first two logs of what remains have a "+" between them so we use the first property:
The remaining two logs have a "-" between them so back to the second property:
which simplifies to:
