Complete the two problems below:
1. Convert 1005.3 to exponential form and explain your answer.
2. Convert 4.87 x 10-6 to ordinary
form and explain your answer. Your
Answer:
1.) Convert 1005.3 to exponential form and explain your answer:
,All number values must be between 1-10. Because this value is greater than 1, the exponent remains
positive.
In order for this to happen, we have to move the decimal three places to the LEFT thus, the exponential
form of 1005.3 is: 1.0053 X 103
2.) Convert 4.87 x 10-6 to ordinary form and explain your answer.
All number values must be between 1-10. Because this value has a
negative exponent, the final answer will be less than 1. In order for this
to happen, we have to move the decimal six places to the LEFT thus:
