How many significant figures does the number 8000 have?

To determine the number of significant figures in the number 8000, it's important to understand the rules for identifying significant figures. Typically, significant figures include all non-zero digits, any zeros between significant digits, and trailing zeros only if they are to the right of a decimal point.

In the case of the number 8000, it is not written with a decimal point, meaning the trailing zeros may not be considered significant under typical conventions. Thus, without additional context, such as a decimal point (which would indicate that the zeros are significant), we typically regard the number of significant figures as being determined by the non-zero digit.

If the number were written as 8000. (with a decimal point), it would indicate that all four digits are significant, leading to four significant figures. However, without the decimal point, only the non-zero digit “8” is considered significant. Therefore, the most conventional interpretation is that there is only one significant figure in 8000.

Hence, the appropriate answer indicating the significant figures would actually be one, but since the response provided indicates four significant figures without clarifying if a decimal point is included, it could lead to confusion depending on context. It's important to clarify how the number is presented, especially in
