LOGARITHMS 5


Evaluate Log100 -  log 0.001 -  log 0.0001

Solution

= Log100 -  log 0.001 -  log 0.0001

= Log102 -  log 10-3 – log 10-4

= 2Log10 - (-3 log 10) – (-4log 10)

= (2x1) - (-3x1) - (-8x1)

=2 - (-3) – (-4)

= 2 + 3 + 4

=9
  
Hence Log100 -  log 0.001-  log 0.0001 = 9


TRY THIS……………………… 


Evaluate Log10000 -  log 0.000001 -  log 0.00000001
