You can calculate logarithms to any base (n) for any number (x) by dividing the natural logarithm of x by the natural logarithm of n, as follows:

Log n(x) = Log(x) / Log(n)

## Пример

```
Sub ExampleLogExp
Dim a As Double
Dim Const b1=12.345e12
Dim Const b2=1.345e34
a=Exp( Log(b1)+Log(b2) )
MsgBox "" & a & chr(13) & (b1*b2) ,0,"Multiplication by logarithm function"
End Sub
