# The mantiss

Mantissa: Every logarithm consist of a fractional part called the mantissa.

Here, The mantissa of log 23750 is 0.3756

Let N = 0.00002375

Divide N by 108 to remove decimal, we get Multiply and Divide N by 1000, we get   Thus, scientific notation 0.00002375 = 2.375 × 10–5

Consider,

log 0.00002375 = log (2.375 × 10–5 )

= log 2.375 + log 10–5

(since, log (a×b) = log a + log b)

= log 2.375 + (–5)

(since, log 10n = n)

Thus characteristic of log 0.00002375 is –5

Thus, Value of log 0.00002375 = –5 + 0.3756 = ̅5.3756
