Question:

find the value of
log 20

Answer:

find the value of
log 20


Answer is 1.3010
==================================================================
The whole number part of a logarithm and the decimal part have been given separate names.
The whole number part of a logarithm is called the CHARACTERISTIC.

The decimal part of a logarithm is called the MANTISSA.


For example, log 5270 = 3.72181; the mantissa is 0.72181 and the characteristic is 3.

Here you have to find out the value of log 20

Here the given number is 20, which is a whole number.
Its a two digit number.

Its charecterisitc is 2-1 (that is number of digits minus one)

So charecteristic is 1

Now for mantissa, with the help of logarithm table you can find out the value
mantissa = 0.3010


So the value of log20 = 1.3010


Hope you found the explanation useful


Regards.
