Help. In a hurry.
I dunno how to do the math tags exactly, but the fraction is 15x^3 over y^5
aww.. first, be calm because stress will kill you..
next, read your notes and recall everything you already know..
i'll do this example completely.. try to study and try to answer the rest..
so, we are left with
i used the first identity i gave.. for the minuend.
then this time, i used the third identity..
can you follow it?
Mankvill: let's have a crash course in logarithms.
If you got multiplication within the ln brackets, you can separate them like that.
Another thing, you can also separate the ln if it had division within brackets:
Notice that when they're multiplied, they ln of each value inside is added. When they're divided, it becomes: ln of the numerator minus ln of the denominator.
Do you follow now? If you do, reread kalagota's answers.
EDIT: Kalagota, didn't see that you posted this already.
