Answer:
ANSWER
(i) log
10
(10×2.791)=log
10
10+log
10
(2.791)
=1+log
10
(2.791)⇒ Characteristic =1
(ii) log
10
(2.871×10
−2
)=−2+log
10
(2.871)⇒ Characteristic =−2
(iii) log
10
(9.87×10
−4
)=−4+log
10
(9.87)⇒ Characteristic =−4
(iv) log(2475)=log(2.475×10
3
)
=log
10
10

+log
10
2.475=3+log
10
2.475⇒ Characteristic =+3
