If log 27 = 1.431, then the value of log 9 is:

A)0.934
B)0.945
C)0.954
D)0.958

• log 27=1.431
  log27= 3log3
  log 3=1.431/3
  log 9=1.431*2/3
  log 9=.954

• log 27=1.431
  log (3)^3=1.431
  3 log(3) =1.431
  log(3)=1.431/3=0.477
  and we can write log(9) =log(3)^2=2 log(3)= 2*0.477 =0.954

• First Given that
  log 27 =1.431
  => log 3^3 = 1.431
  => 3log3 = 1.431 => log 3 =1.431/3
  Now,
  log 9 => log 3^2 => 2 log 3 = 2 * 1.431/3
