How do you simplify this equation?

A log is just an exponent (power), rosala..let me demostrate....

For example  log₂ (8)   says this....what power (exponent) do we put on "2" (called the base) to raise this to 8 ?? The answer is "3.'   This is because 2³ = 8  !!!

The most common bases are 10 and "e"  (e ≈ 2.718)  ...Normally, the base 10 log is notated without the base - the base is understood to be 10 - and the base "e" log is notated as "ln"  ......called the "natural log".......the natural log base is extremely useful in many scientific applications.  So base 10 log  of 100 would be notated as  log(100) and the natural log of 100 would be notated as ln(100).

(Note.....We can actually use any positive number - except 1 - as a base!!!)

There are also some property of logs, but that's probably enough for today!!! I've got to go someplace, but here's a presentation by Purplemath that's pretty good !!! .......http://www.purplemath.com/modules/logs.htm

Hope that helps some.....!!!

Assuming that we have   log(4) + log(32)  we have

log(4 * 32) = 

log (128)

CPhill i still havent yet studied what log is but im keen to know what it is!if u dont mind can u please tell me what it is and how do we solve its problems and what are some methods of it!?

Thank you so much for telling me this CPhill!it was all quiet interesting!i have never felt so much interest in Maths after i felt after seeing this log question!A point for u!

And some flowers as well!
