LOGARITHMS-5



Simplify        Log0.000001
                        Log(1/100)

Solution

=    Log0.000001
       Log(1/100)

=    Log10-6
       Log100-1

=    Log10-6
       Log(102)-1

=    Log10-6
       Log10-2

=    -6Log10
       -2Log10

=    -6
       -2

=    3


Hence           Log0.000001         =  3
                        Log(1/100)
