How many significant digits are in this numer 74.30?
Some answers have ongoing digits and therefore have unlimited significant digits. For example, 100/3 is 0.3333333... and the 3s are unlimited. Therefore, the number has an un…limited amount of significant digits.

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 - the first three zeros are not significant.
Two - the zeros are placeholders.
It varies depending on the base you are using. The standard is the decimal system (because of the 10 fingers on our hands) 0-9. Some other used systems (especially for compute…rs) are binary 2, octal 8, hexadecimal 16 using the digits: 0-9,A-F.
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 figures…) 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.
