How do I round 8164 to the 4 decimal point?

8.1640 * 10^3

Step-by-step explanation:

Question doesn't make sense because there are no decimals. But you can convert to scientific notation.

Yeah, I agree with letsgoplayd. Your answer doesn't make any sense because 8164 is not a decimal. But we can look at another example:

8164.45678

In this case, the number rounded to the 4th decimal point (ten thousandths) would be

8164.45680

Because the digit after the 7 is 8, we should round the "78" part to "80".

These two rules will help:

5 or more, raise the score (add 1 to the digit, and let the digit directly behind it become 0.)

4 or less, let it rest (keep the digit, and let the digit directly behind it turn to a 0.)

Hope this helps! :)
