Answer 2

Sig figs are the significant numbers. in A the zero before the decimal isn't significant, so it is not counted.

Answer 3

In D the last zero is significant because there is not a decimal before it.

Answer 4

c and d are also three

Answer 5

C is 4 because the zero after the decimal and before 7 is significant, if you got rid of it it would change the value.

Answer 6

D is four because if you take the last zero out it changes the value. if it was 105.0 instead of 1050 it would be 3
