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.
