how many significant figures in 200600

4 you don't count the end ones unless there is a decimal point

To determine the number of significant figures in 200600, we need to follow these rules:

1. Non-zero digits are always significant. In this case, there are four non-zero digits: 2, 6, 0, and 0.

2. Zeros between non-zero digits are considered significant. There are no zeros between non-zero digits in 200600.

3. Leading zeros (zeros at the beginning) are not significant. There are no leading zeros in 200600.

4. Trailing zeros (zeros at the end) may or may not be significant, depending on the presence of a decimal point. If there is a decimal point, trailing zeros are counted as significant. In this case, there is no decimal point, so trailing zeros are not significant.

Based on the above rules, there are four significant figures in 200600: 2, 6, 0, and 0.
