Five - any zeros after the decimal are significant unless they're placeholders. Any zeros between significant digits are significant.
There is one significant figure (which I assume you are referring to). However there are 7 digits involved, of which all are significant. Each digit is important and special… in its own right. None should be singled out as being different, as that is Digitist. * * * * * Leaving aside the political correctness of the anti-digitism, the number of significant digits depends on the context. In the above example, if it is known that the number is not 3,999,999 nor 4,000,001 then all seven digits are significant. If it is known that the number is 4,000 thousand (not 3,999 thousand or 4,001 thousand) then there are 4 sig digs.
Just one, the first 5. * * * * * No. All three digits are significant.
One - the zeros are placeholders unless indicated.
Four. Unless the trailing zero is purely for conventional purposes - for example, expressing a currency value.
Answer: four. All written decimals are significant (even if it is 0). However if you have a physics computation where one number turns out to be x = 2.0 (2 significant fi…gures) and the other turns out to be y = 37.15 (4 significant figures), then to compute the product x*y you should take the least of these significant numbers you are using. Hence, you will find that x*y = 2.0 * 37.15 (= 74.30) = 74 (rounded to the nearest number with 2 significant digits only.) So, it depends on the context you are using this number in.
