Answer 2

The number of significant figures are as follows:

1) 308 - 3

2) 1.004 - 4

3) 002 - 1

4) 6.023 10³​ - 4

• The zeros at the beginning of a number are not considered as significant figures as in the case of 002, here only '2' is considered as a significant figure, while the zeros at the starting are not.
• In 1.004, the zeros are placed between the digits, therefore it is a significant figure.
• In 6.023 10³ only the digits in 6.023 are considered as significant figures while in 308 all the digits are considered as significant figures.
