Question

characteristic part of log 35.87 is​

Answer 1

Let's take a number N>0
Then, suppose the value of log10​(N)  consist of two parts 
One an integral part, the other  a proper fraction.
The integral part is called the Characteristic and the fractional or the decimal part is called the Mantissa.
Ex: 
log10​(15)=1.176=1+0.176
In 1.176, the Integral part is 1 and the decimal or fractional part is 0.176
So for the number log10​(15) 
The Characteristic is 1 and the Mantissa is 0.176

Answer 2

The integral part of a common logarithm is called the characteristic and the non-negative decimal part is called the mantissa.

for u r question 1.55473, then 1 is the characteristic and 55473 is the mantissa of the logarithm.
