To solve the problem while observing significant figure rules, we need to consider the number of significant figures in each value involved in the calculations.1. **Multiplication:
** - The number 125 has 3 significant figures. - The number 45.3 has 3 significant figures. - When multiplying, the result should have the same number of significant figures as the factor with the fewest significant figures, which is 3 in this case. Calculation:
Rounding to 3 significant figures:
2. **Scientific Notation:
and
** - The number
has 1 significant figure. - The number
has 2 significant figures.3. **Given Values:** - The number 5662.5 m is given with 5 significant figures. - The number
has 3 significant figures.In summary, when performing operations, ensure that the final answer reflects the correct number of significant figures based on the initial values used in the calculation. For the multiplication example provided, the result rounded to the appropriate number of significant figures is 5660.
