Question

No additional details.

Answer 1

Round it up to 3300 and write it in scientific notation as 3.30 x 10³.  That has 3 significant figures.  Note that is not the same as 3.3 x 10³ or 3.300 x 10³, because the former has only 2 significant figures while the latter has 4 significant figures.  They all imply an uncertainty of 1 unit in the digit on the right, and that is a different quantity in each case.

 

Answer 2

Significant figures means the accuracy of the number.  You need to input 3 digits after the decimal point.

 

3297 = 3297.000
