Question

What is 2648 to two significant figures?​

Answer 1

2.6×10^3 is the answer

Answer 2

Answer:

2600

Step-by-step explanation:

To answer this question we need to write down the rules governing significant figures.

They are as follows :

1) Any number that is not a zero is significant.

2) Any zero between two non zero integers is significant.

3) Any zero before a decimal point is not significant.

4) Any trailing zeroes after the decimal point are significant.

0.500 = the zeroes are significant.

Based on the rules above we can write the number above to 2 significant figures.

We round it off to get :

2648 = > 2600

The zeroes are not significant and hence 2600 is in 2 significant figures.
