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
