Question

If log 27 = 1.431, then the value of log 9 is
A) 0.754
B) 0.854
C) 0.954
D) 0.654

Answer 1

Answer:   C) 0.954 

Explanation:

log 27 = 1.431
log(33)33 = 1.431
3 log 3 = 1.431
log 3 = 0.477
log 9 = log(3232)= 2 log 3 = (2 x 0.477) = 0.954

Here is your answer.

The answer is Option C) 0.954

Explaination:

$log(27) = 1.431 \\ \\ log(33) 33 = 1.431 \\ \\ 3 log(3) = 1.431 \\ \\ log(3) = 0.477 \\ \\ log(9) = log(3232) = 2 log(3) = (2 \times 0.477) \\ \\ = 0.954$
