Question

Round off 3259 to 3 sig figs

Answer 1

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:

`3259\approx3260`

Therefore, the number rounded off to 3 significant numbers is:

3260

ANSWER:

3260
