0.00849 contain_ significant figures

Dear Student,

0.00849
Here we apply two rules
1)All non zero digits are significant.
2)If the number is less than zero, zeros on the right of the decimal point which comes before the first nonzero digit are not significant.

Hence ,two zeros after the decimal point are not significant.8.4 and 9 are significant.
No of significant digits = 3

Regards.
