Maths help its quite esay but not !?

Question

what is 9506 to 3 significant figures?

Answer 1

it's 9510

the 3 most significant digits of the number are 950 so if you were rounding off the result would be 9500. However, since the 4th digit is 6 then the result is 9510 as the 4th digit gets rounded up.

Answer 2

it is 9510 since 0 is not a significant figure because it has no value but if not written behind a number like that it loses its value

Answer 3

9510

the 0 at the end is not a significant figure, more of a "spacer" to make sure the size of the number does not change, i.e. going from 9506 to 951!!

Answer 4

9510 because the six is rounded up to ten .  

Answer 5

9510
