Question

What is the solution to the problem expressed to the correct number of significant figures

Answer 1

I don't know what the problem is, but here are some rues to help you out:

1. All non-zero figures are significant
2. When a zero falls between non-zero digits, that zero is significant.
3. When a zero falls after a decimal point, that zero is significant.
4. When multiplying and dividing significant figures, the answer is limited to the number of sig figs equal to the least number of sig figs in the problem.
5. When adding and subtracting, the answer is limited to the number of decimal places in the number with the least number of decimal places.
