Verified step by step guidance

Understand the concept of significant figures: Significant figures are the digits in a number that are known with certainty plus one digit that is uncertain. They are important in scientific measurements because they indicate the precision of a measurement.

Identify the rules for determining significant figures: Non-zero digits are always significant, any zeros between significant digits are significant, leading zeros are not significant, and trailing zeros in a number without a decimal point are not significant.

Apply the rules to the number 10: The number 10 has one non-zero digit, which is '1'. The trailing zero in this case is not considered significant because there is no decimal point.

Conclude the number of significant figures: Based on the rules, the number 10 has only one significant figure, which is the digit '1'.

Consider the context: If the number 10 were written as 10.0, it would have three significant figures because the decimal point indicates that the trailing zeros are significant.
