The calculator makes it possible to calculate on line the **logarithmic expansion** of an expression that
involves logarithms : it is used both for the neperian logarithm and for the decimal logarithm.
The calculator makes it possible to do symbolic calculations, it is therefore possible to combine numbers and letters.

The calculator can make **logarithmic expansions of expression** of the form
ln(a*b) by giving the results in exact form : thus to expand
`ln(3*x)`, enter
expand_log(ln(3*x)),
after calculation, the result is returned.

The calculator can also make **logarithmic expansions of formula** of the form
`ln(a/b)` by giving the results in exact form : thus to expand
`ln(2/x)`, enter
expand_log(ln(2/x)),
after calculation, the result is returned.

The calculator can also make **logarithmic expansions of formula** of the form
`ln(a^b)` by giving the results in exact form : thus to expand
`ln(x^3)`, enter
expand_log(ln(x^3)),
after calculation, the result is returned.

The calculator makes it possible to obtain the logarithmic expansion of an expression.

- expand_log(ln(a*b)) returns `ln(a)+ln(b)`
- expand_log(ln(a/b)) returns `ln(a)-ln(b)`
- expand_log(ln(a^2)) returns `2*ln(a)`
