Back

This allows you to convert logarithms to a different base.

Front

Properties of logarithms: log_b(xy) = log_bx + log_by

Back

This property allows the multiplication of arguments to be expressed as addition.

Front

Properties of logarithms: log_b(x/y) = log_bx - log_by

Back

This property allows the division of arguments to be expressed as subtraction.

Front

Properties of logarithms: log_b(x^n) = n * log_bx

Back

This property allows the exponent of an argument to be brought in front as a coefficient.
