Rule No 2:
if x < 1, characteristic = - [(No. of zeros immediately following the decimal point) + 1].
Characteristic of log0.435 is……….
a) 0
b) 4
c) 3
d) -1
Explanation:According to Rule no 2: x <1 then we count number of zeros immediately following the decimal point like (there is no zero after decimal in the given number 0.435 in the right side of decimal) so -[0+1]= -1
Characteristic of log0.0435 is……….
a) 0
b) 4
c) -2
d) -1
Explanation:According to Rule no 2: x < 1 then we count number of zeros immediately following the decimal point like (there is one zero after decimal in the given number 0.0435 in the right side of decimal) so -[1+1]= -1-1= -2
Characteristic of log0.000435 is……….
a) 0
b) -4
c) -2
d) -1
Explanation:According to Rule no 2: x < 1 then we count number of zeros immediately following the decimal point like (there is three zero after decimal in the given number 0.000435 in the right side of decimal) so -[3+1]= -3-1= -4
