4. Pablo divided (6 x 10^8) by (2 x 10^-4), and got a final answer of 3 x 10^-2. Explain what mistake Pablo made, and give the correct solution.
Pablo made a mistake when dividing the numbers with exponents. When dividing numbers with exponents, you subtract the exponents.
The correct solution would be:
(6 x 10^8) / (2 x 10^-4) = 6/2 x 10^(8-(-4)) = 3 x 10^12
So, the correct answer should be 3 x 10^12, not 3 x 10^-2.
