Question

1. State the number of significant figures in each of
the following
(a) 39 018
(b) 0.028 030
(c) 2900 (to the nearest 10)​

Answer 1

Step-by-step explanation:

(a) 39018 -------> 5 Significant figures as 0 is between non zero digits.

(b) 0.028030 -----------> 5 Significant figures as all zeros before will not be counted as they are before non zero digits and zero after non zero digits in decimals will be counted as significant figures.

(c) 2900 ((nearest 10) ---------> 2900)

=> 2900 will have 3 significant figures as we have to count the unit at 10 as well as mentioned.
