Question

What are these numbers in scientific notation ?

Answer 1

Count how many places to the left you need to move the decimal point to get one digit to the left of the decimal point. That number of places is the exponent you use for the power of 10 when you write the number in scientific notation.

For example, 200. = 2.00×100 = 2.00×(10×10) = 2.00×10²

In scientifc notation, your numbers are

• 5.7909×10⁷ kilometers
• 1.082×10⁸ kilometers
• 1.496×10⁸ kilometers
• 2.2794×10⁸ kilometers
• 7.7833×10⁸ kilometers
