Final answer:
To write measurements in scientific notation and convert to SI base units, express the numbers in scientific notation and then convert to kilograms for mass.
Step-by-step explanation:
Writing the given measurements in scientific notation and converting them into SI base units involve two steps. First, we express the numbers in scientific notation. Following that, we convert the given units to the corresponding SI base units. Here's how we do it for each example:
Remember that the kilogram is the SI base unit for mass. To convert grams to kilograms, we divide the number of grams by 1,000 (since 1 kg = 1,000 g).
