If log 27 = 1.431, then the value of log 9 is:
A. 0.934
B. 0.945
C. 0.954
D. 0.958

• C. 0.954
  
  log 27 = 1.431
  log(3³) = 1.431
  3 log 3 = 1.431
  log 3 = 0.477
  log 9 = log(3²)= 2 log 3 = (2 x 0.477) = 0.954

• C. Because. Log+Log9 =1.431
• 4 years agoHelpfull: Yes(1) No(0)
• log 27 = 1.431
  log (3) ^ (3) = 1.431
  3 log 3 = 1.431
  Multiply and divide by 2
  (3*2 log 3) / 2 = 1.431
  3 log 9 = 2.862
  log 9 = 0.954
• 4 years agoHelpfull: Yes(0) No(0)
• 0.954
  Log 27=1.431
  Log(3*3*3) =1.431
  Log 9+log 3=1.431
  Log 3^3=1.431
  3 log 3=1.431
  Log 3=0.477
  Log 9=log3^2=2log3=0.477*2=0.954
• 4 years agoHelpfull: Yes(0) No(0)
• log(3)^3=1.431
  log3=0.477
  log 9 = log 3 + log 3
  log 9 = 0.954

• 3 log 3=1.431
  
  log 3=1.431/3=0.477
  
  log 3*3=0.954 (0.477*2) (square one side then we can multiply with another side)
  
  like
  log 2=0.30129
  log 2*2=0.30129*2

• log27=1.431
  3log3=1.431
  log3=0.477
  log9=2log3 then 2*o.477=0.954
• 4 years agoHelpfull: Yes(0) No(0)
• C. 0.954
  
  log(9*3)=1.431
  log(9)+log(3)=1.431
  log 9=1.431-0.477
  =0.954

• Log27=3*log3
  Log3=1.431/3
  Log9=2*log3
  =0.954
