how to take log and anti log

The web2calc on the home page has log and 10^x displayed all the time at the bottom of the calculator.

If you put your curser over either of these then ln, e^x appears below and log₂,  2^x  appears below that.

So log base 10 is log and antilog base 10 is  10^x

Log base e is ln and antilog base e is e^x

Log base 2 is log₂ and antilog base 2 is 2^x

You can also type these straight into the input area at the top of the calculator.

I am sure that if I have said anything incorrect someone will correct me.  

You take a logging company and throw a bunch of angry protesters at it!

I'm sure someone will give you a proper answer. :)

Use the "log" or the "ln" key when you want to find the log of something and for anti-logs, use the 10^x key.

if y = log(3) [assume base of 10] --> y= 0.4771212547196624.

The anti-log would be 10^3 = 1,000.
