What does to 2 significant figures mean?
for eg:Round 1578 to 1 Significant place(S.f)= 2000 as you have to round the number so that there is one whole number followed by 0s 1578 to 2,s.f=2600 as you have two number rounded to the nearest ten,Followed by 0s I hope i helped
How do you evaluate significant figure?
A significant figure is a bit like a decimal place, in that just how a maths question may ask for the answer 'to 2 decimal places' it may also be answered to '2 significant figures'. For example, say you have the answer: 3.1415926 To 1 decimal place it would be: 3.1 (because you round the 4 after the 1 down, because it is less than 5), because there is 1 digit after the decimal place (.) To (a certain amount) of significant figures, however, means the total amount of digits/numbers in the answer, for example: To 3 significant figures, the answer would be: 3.14 because there are now just 3 digits in the answer. However, a '0' does not count as a significant figure if it is before/after a set of regular (1-9) numbers (but it does count if it is in-between). For example: 0.00000454 This is still to 3 significant figures, because the '0's are before the other numbers, and so do not 'count'. The same can be said for: 45400000000 This is still to 3 significant figures, because the '0's are after the other numbers, so they do not count. However: 400045 This is NOT to 3 significant figures, because the '0's are IN BETWEEN the other numbers, and so they DO count as significant figures. Hope I helped :)
