See explanation. Other contributors may chose to offer other potential examples.

Explanation:

It all depends on the numbers.

Suppose you had #3^56xx12^87#

#color(blue)("One possible approach could be:")#

#log(3^56)+log(12^87)" "->" "[56xxlog(3)]+[87xxlog(12)]#

#=>3^56xx12^87" "->" "log^(-1)(color(white)(.)[56xxlog(3)]+[87xxlog(12)]color(white)(.))#

In the 'old days' they called this the 'antilog' which is the reversing process so that you go from log back to source number
