Question

How many significant figure should be present in 600?

Answer 1

It looks like 1 significant figure.

Explanation:

Significant figure rules are important and blah. Basically think of this number as a number in a series you are counting. Without a decimal point, the previous number would be 500, the following number would be 700. 100, 200, 300, 400, 500, 600, etc. In this way, there is only 1 significant figure.

If it had been 600., then the next number would be 601, then 602, etc, and 600. would have 3 significant figures.

If it had been 600.0, then the next number would be 600.1, 600.2, etc, and 600.0 would have 4 significant figures.

Maybe that helps.
