LOGARITHMS K3

 

Simplify        Log0.000001

                        Log(1/1000)

 

Solution

 

=    Log0.000001

       Log(1/1000)

 

=    Log10^-6

       Log1000^-1

 

=    Log10^-6

       Log(10³)^-1

 

=    Log10^-6

       Log10^-3

 

=    -6Log10

       -3Log10

 

=    -6                        [since Log 10 and Log 10 cancel out]

      -3

 

=    2

  

Hence           Log0.000001   =   2

                      Log(1/1000)
