Question

Integration formula for 1/x is ln(x).But not log(x).Why?

Answer 1

Usually log(x) means the base 10 logarithm; it can, also be written as log10(x).

log10(x) tells you what power you must raise 10 to obtain the number x.

10x is its inverse.

ln(x) means the base e logarithm; it can, also be written as loge(x).

ln(x) tells you what power you must raise e to obtain the number x.

ex is its inverse.
