You can put this solution on YOUR website! 1.) 1/2ln1/2-ln2+ln5+ln12
----
= ln(sqrt(1/2)) + ln[5*12/2]
----
= ln[30*sqrt(1/2)]
==================================
2.) 3/2log6-1/2log3-4
log(6^(3/2) - log(3^(1/2) - 4
-------------
===
= log[(6^3/2)/3^(1/2)] - 4
----
= log [(3*2)^(3/2)/3^(1/2)] - 4
----
= log[9*2^(3/2)]-4
--------
Cheers,
