the exponent of the power to which a base number must be raised to equal a given number; log: 2 is the logarithm of 100 to the base 10 (2 = log10 100).

what would be the logarithm of 200?

-54. This is fact. Write it down on your homework!

always depends on the base. It's 2.3 to the base of 10 because 10^2.3 = 200

Get yourself a TI-83+ calculator, IronTurk.

Don't understand the question.
If you take the equation y=10^x, then x=log10(y).
It's just the inverse function of the exponential function.

Ah OK, it's usually calculated by developing it into a mathematical series. It's not easy to calculate.

Deshalb hasste ich die Uni. Diesen Sch...dreck wirst du dein ganzes Leben nie brauchen, es sei denn du willst Mathe-Lehrer werden um den Sch....dreck wieder an andere weiterzugeben die ihn ihr ganzes Leben nie brauchen werden (es sei denn sie wollen Mathe-Lehrer werden, um den Sch...dreck an andere.....).

Let me know when you need help on Fourier Transforms. Used those in my Masters thesis at USC. (wait, wrong thread)

Good explanation. I like yours more than Wiki.
