LOGARITHMS 5


Evaluate Log1,000,000,000 +  log 0.01 + log3243

Solution

= Log1,000,000,000 +  log 0.01 + log3243

= Log109 +  log 10-2 + log33-5

= 9Log10 +  (-2log 10) + (-5log33)

= (9x1) + (-2x1) + (-5x1)

= 9 + (-2) + (-5)

= 2

Hence Log1,000,000,000 +  log 0.01 + log3243 = 2

TRY THIS……………..



Evaluate Log100,000,000 +  log 0.0001 + log381
