### Function : expand_log

#### Summary :

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

Expand_log online

#### Description :

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.

# Calculation of expression of the form ln(a*b)

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.

# Calculation of expression of the form ln(a/b)

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.

# Calculation of expression of the form ln(a^b)

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.
