Help with Logarithms

[sanjaythegr8]

hey guys,

i hve test tomm on financial management n i hve to revise logs which we had done in school. i m getting very confused as where to put the decimal point or 1 bar...and i cant find material to revise the same. Can any1 pls post a link explaining logs in simple words.

How to solve this equation:

In(Vs/E)

where : In = natural log, i.e, to the base "e", Vs = 165, E= 150

Thx in advance

ln(A/B) = ln(A) - ln(B)

ln(A*B) = ln(A) + ln(b)

So,

ln(Vs/E) = ln(Vs) - ln(E)

This is all you need to know

thx a lot

is this correct:

In(Vs/E) - where Vs=165, E=150

=log 1.1 / log e

thx a lot

is this correct:
In(Vs/E) - where Vs=165, E=150

=log 1.1 / log e

It is correct.
ln(165/150) = ln(165) - ln(150) = ln(1.1)(165/150 = 1.1)
ln e = 1
So,

ln(165/150) = ln 1.1 / ln e

Sanjay, you can use Wolfram Alpha for any mathematical equation.

ln(165/150) - Wolfram|Alpha

It's pretty handy and saves time.
