It looks like you’re working on a problem related to significant digits and evaluating expressions while applying the correct number of significant figures.

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: $51,700 \times 0.26398$ and $19,600$

Question 11:

Evaluate the expression and report the correct number of significant digits: $1.547 \times 0.00862 \times 4.390$ and $0.0586$

To correctly solve these, you need to apply the rules for significant digits in multiplication and division:

Rules for Significant Digits:

1. Multiplication and Division: The result should have the same number of significant digits as the number with the least significant digits in the expression.
2. 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?
