8000000

The 5 after the 7 indicates the 7 should be rounded up to 8.

That's a telephone number. Have you not heard of common sense?

7,523,987

The answer of 8,000,000 is not entirely satisfying as obviously, we don't know how many significant figures it contains.

Better answer is:

8×10^6

Those aren't decimal points, they are commas...to help to read the number

The last dot is a full-stop or period I'll remove it if it bothers you.1234567 is difficult to read, but 1,234,567 is much easier.8000000 is the same as 8,000,000 or 8 million! - Log in to reply to the answers

Look to the right of the 1 sigfig, it's a 5

The rule: If 5 or more, round up

So 8 000 000 or 8 million or 8. x 10^6
