difference of lg vs log

Question

Is there a difference between lg and log because when looking up lg vs ln sometimes it's referenced as lg and other times as log and google has been no help with it.

Answer 1

Log refers to base 10: if x = log(y) then 10^x = y
Ln refers to base e: if x = ln(y) then e^x = y
Lg refers to base 2: if x = lg(y) then 2^x = y

Hope this helps!
