In the image you uploaded, we see two questions, with the following expressions for evaluation:
Question 10:
You need to evaluate the expression and report the correct number of significant digits: and
Question 11:
Evaluate the expression and report the correct number of significant digits: and
To correctly solve these, you need to apply the rules for significant digits in multiplication and division:
Rules for Significant Digits:
- Multiplication and Division: The result should have the same number of significant digits as the number with the least significant digits in the expression.
- Addition and Subtraction: The result should have the same number of decimal places as the number with the least number of decimal places.
Would you like a detailed solution for each of these questions, explaining the rules and the final results step by step?
