If log 2 = 0.3010 and log 3 = 0.4771, log5 512 has the value:
A. 2.870
B. 2.967
C. 3.876
D. 3.912
Answer:C
If log 2 = 0.3010 and log 3 = 0.4771, log5 512 has the value:
A. 2.870 B. 2.967 C. 3.876 D. 3.912
Explanation: log5 512 = log 512 divided by log 5= log 29/10/2 = log 29/10/2 = log 29/10/2 = log 29/10/2 = log 29= 9 log 2/log 10 - log 2 log 2 log 2 log 2 log 2 log 2 log 2 log 2 log 2 log 2= (0.3010)/1 - 0.3010 = (9 x 0.3010)/1 - 0.3010= 2.709/0.699= 3.876 = 2709/699.
