Given the number:
3259
Let's round off the given number to 3 significant figures.
To round off any number, apply the following conditions:
0. Non-zero numbers are significant numbers.
,1. Zeros between two non-zero numbers are significant.
,2. Leading zeros are not significant.
,3. Zeros at the end are only significant if there is a decimal point after it.
Hence, to round off the number, given that the fourth significant number 9 is greater than 4, add 1 to the third significant number (5) and rewrite 9 as zero.
We have:
[tex]3259\approx3260[/tex]Therefore, the number rounded off to 3 significant numbers is:
3260
