four The presence of the decimal point tells us that all 4 digits are significant.
There are two sig figs in 8.4. (There would be two no matter what the units were, such as 8.4 kg for example.)
There are three sig fig.(The final zero is significant as it is present when it would not normally be written.)
It depends on how many significant digits you want to round it off to.
Integers ending in zero are always ambiguous. It is not possible to tell whether the given number is accurate to the nearest hundred (2 sig digs) or to the nearest unit (4 sig digs).
It has six sig figs
It has 3 sig. fig.
it has 6 sig digits (405608) the 0.00 dont count
1) Look at the two numbers you are multiplying 2) Find both their number of significant digits 3) Multiply both numbers together normally 4) Round your answer to the same number of significant digits of the least number in the first two factors 250 x 185 250 had 2 sig. digits------ 185 has 3 sig. digits 250 has the least number of sig. digits (2) Final answer has to have 2 sig. digits Normal answer: 46250 With rounding of sig. digits: 46000

There are 3 sig fig.
3 sig figs.
Just one. The trailing zeros are not significant. * * * * * Not true. Integers with trailing 0s are ambiguous. You cannot differentiate between 500o as a number rounded to the nearest thousand (1 significant digit), or the nearest hundred (2 sig digits), or the nearest ten (3 sig digits) or the nearest unit (4 sig digits).
4 Since the first number has 4 sig digs and the second has 7, you have to use the least number of sig digs.
5 has 1 sig fig.
Three of them. No. There are 5 sig. figs in 1.5300 !!!
four The presence of the decimal point tells us that all 4 digits are significant.
