A scientist measured the exact distance between two points on a map and came up with the following number: 0.04000 km.
stellarik [79]

Answer:

The first zero after decimal point and 4 only

Step-by-step explanation:

For this case, the significant digits are only 0.04 but if it was 0.0400005 then all the other zeros would have also be considered significant.
