Answer 2

Answer:

3.40 - 3 Significant figures  

0.005032- 4 Significant figures

Explanation:

All non-zero digits are significant

Zeros between non-zero digits are significant ( example: 40025 , all four digits are significant )

Trailing zeros in a number with a  decimal point  are  significant ( example : In 4.500  all four digits are significant )

The zeros on the right of decimal  point but to  left of the first non-zero digit is not significant ( example: in 0.005306 , the underlined zeros are not significant)
