What is the difference between log (x), ln (x), and lg (x)?

Log X vs ln x

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

Step-by-step explanation:

ln(x) is always natural log, or log base e.

log(x) is sometimes log base 10, but very often in higher math, it is used as natural log, or log base e.

lg(x) is log base 2.
