Question

Characteristic of log 0.0003798 is
(B)
(C)
3
4​

Answer 1

Explanation:

You first see antilog table

0.3798*10^3

then, see log table 37 -2393

approx 3

so answer is 3

Answer 2

Given:

log 0.0003798

To Find:

The characteristic of log 0.0003798 is

Solution:

we know,

log 0.0003798 = log (3.798 x 10⁻⁴)

                          = log 10⁻⁴ + log 3.798

                          = -4 log 10 + log 3.798

                          = -4 + log 3.798         (∵ log 10 = 1 )

Hence, The characteristic of log 0.0003798 is -4.
