chapter 6.2 Logarithms

Logarithms.

First of all, i would like to share a pretty good link for people who wants to learn more about log and exponential function ( from the previous post).

logarithms ?
The logarithm of a number is the exponent by which another fixed value, the base, has to be raised to produce that number. For example, the logarithm of 1000 to base 10 is 3, because 1000 is 10 to the power 3: 1000 = 10³ = 10 × 10 × 10. More generally, if x = b^y, then y is the logarithm of x to base b, and is written log_b(x), so log₁₀(1000) = 3.

The picture shown is a basic formula for a log.


More over, i would like you all to visit the link that ive posted right after this paragraph to increase your understanding on logarithm; as it may be the hardest chapter if you didnt get it really well.
