Explanation:

Step1: Identify the number of decimal places

For addition and subtraction, the result should be rounded to the least number of decimal places.

• \(8.823\) has \(3\) decimal places.
• \(3.42\) has \(2\) decimal places.

Step2: Determine the number of significant figures based on decimal - place rule

After subtraction \(8.823−3.42 = 5.403\). But we round to \(2\) decimal places (because \(3.42\) has \(2\) decimal places). So the result is \(5.40\). The number \(5.40\) has \(3\) significant figures.

Answer:

\(3\)
