how to calculate log

Answer 1

What's the question?

Answer 2

a log is the power or exponent to which the base must be raised in order to produce the number.

for a example

Log 8 base 2 = 3 because 2^3 = 8

0.903089987/ 0.301029996 = 3

there use because you can multiply or divided by adding and subtracting

example :

2 * 3 = 6

log(2) + log(3) = log(6)

0.301029996 +0.47712126 = 0.778151250384

10^ 0.778151250384 = 6 ( the 10^ is the antilog or arc log fuction )

6/2 = 3

log(6) - log(2) = log(3)

0.778151250384 - 301029996 = 0.47712126

10^ 0.47712126 = 3
