To determine the number of significant figures in each of the given numbers, follow these steps:
a. 234: There are three digits in the number, so there are three significant figures.
b. 2500: There are four digits in the number, but trailing zeros that are not followed by a decimal point are not significant. Hence, only the first two zeros are significant in this case. Therefore, there are two significant figures.
c. 0.0034: Non-zero digits are always significant. So, there are two significant figures in this number.
d. 12.00: All the digits in the number, including the trailing zeros after the decimal point, are significant. Therefore, there are four significant figures.
e. 0.01010: Similar to example c, non-zero digits are significant. So, there are four significant figures in this number.
By applying these rules, you can determine the number of significant figures in any given numerical value.
