log square root of x(square root of y(square root of z))

[tpryor]

i don't even know if i'm saying that right...or how to type it on here...

its log ( then the square root of x times the square root of y times the square root of z, but the square root of z is nested under the square root of y and the square root of those two is nested under the square root of x...

I've seen people type out equations on here so it looks like its coming out of a textbook..is there some kind of special program you can download that does that, or do you just have to know the right codes...?

by the way...what i'm trying to do with this is expand the logarithm...

thanks for your help...

Use the fact

\(\displaystyle log (\sqrt{a}\ ) = log (a^{1/2}) = 1/2 \cdot\ log(a)\)

and

log (a * b) = log(a) + log(b)
