1. Log(2)5 +log(2)(X^2-1) - log(2) (X-1)



2. 3^2log(3)5



3. 2log(10) root of X +3log(10) X^1/3



Solving for the indicated variable... solve this equation for A..


4.x/a + y/b + z/c=1

The LCD is abc. Multiply through by abc:

No need to post on different topics... nor twice in the same topic

Anyway, I wasn't aware of that, and I already answered it there.

galactus, the question was 'solving for a', though I believe it is 'making a the subject of formula'.



Send everything except x/a on the right.



Make as a single fraction:



'Cross multiply everything' or invert everything:



Then, multiply by x:

So right:o

I solved for x. Oh well, the method is pretty much the same.

I tried giving you a greenie, but of course, it won't let me. I have been spreading it around, but it still won't allow me to give you a greenie. :confused:

Same thing here for the 'Derivatives' thread... :( Your recent greenie on Survivorboi's thread I gave you prevents me from giving you another one now. I have to greenie some more people...

I don't like that. It's bogus, man:)
