how to solve x = antilog (-5.4)
The digits before the decimal becomes the mantissa.
antilog(-5.4)
Characteristic=5
Mantissa=0.4
To find the value of antilog negative value..
- Ignore the negative sign.
- Add one to the characteristic and write it in the negative power of 10. i.e. 10-6
- substrate characteristic from 1 and write it in the multiple of 10-6.
we get..
(1-0.4)x 10-(5+1)
=0.6 x 10-6
Add we will look for the value in 0.60th row, 0th column of the antilog table, which is 3989.
Therefore, antilog(-5.4)=3.989 x10-6
