If log 27 = 1.431, then the value of log 9 is:
Answer: Option
Explanation:
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.

log27 = 1.431
log3^3 = 1.431
3 log 3 = 1.431
log 3 = 1.431/3
log 3 = 0.477
Find log 9.
log 3^2.
2log 3 and the value of log3 is 0.477.
2 * 0.477 = 0.954.
log3^3 = 1.431
3 log 3 = 1.431
log 3 = 1.431/3
log 3 = 0.477
Find log 9.
log 3^2.
2log 3 and the value of log3 is 0.477.
2 * 0.477 = 0.954.

Log 9 = log(27/3).
= Log 27 - log 3.
= 1.431 - 0.4771 // log 3 = 0.4771,
= 0.954.
= Log 27 - log 3.
= 1.431 - 0.4771 // log 3 = 0.4771,
= 0.954.

Its given 1.431 i.e the point is at before three number. Hence we can write:
= 1431/1000.
Now its divide by 3.
= 1431/3-1000.
i.e 477/1000 = 0.477.
Because the numbers of zero three hence the point comes in before three number.
= 1431/1000.
Now its divide by 3.
= 1431/3-1000.
i.e 477/1000 = 0.477.
Because the numbers of zero three hence the point comes in before three number.

Please tell me how we can divide the value with the point I don't know how to divide with a point value like 3.

log27 = log(3*9) = log3+log9.
So, log9 = log27-log3.
log9 = 1.4310-0.4771.
log9 = 0.9539 ~ 0.954.
So, log9 = log27-log3.
log9 = 1.4310-0.4771.
log9 = 0.9539 ~ 0.954.

@Arvind.
Here, 3* log3 = 1.431.
Then,
1.431/3 = 0.477.
Here, 3* log3 = 1.431.
Then,
1.431/3 = 0.477.
