1. Introduction

Since 0.749 is a number less than one, n is a negative integer. In this case, n  1.
Combining the above two steps:
0.749  7.49  101
(b) Express 802.6 in scientific notation.
Solution: The decimal point must be moved two places to give N, a number between 1 and 10. In this case,
N  8.026
Since 802.6 is a number greater than one, n is a positive integer. In this case, n  2.
Combining the above two steps:

802.6  8.026  102

(c) Express 0.000000621 in scientific notation.
Solution: The decimal point must be moved seven places to give N, a number between 1 and 10. In this case,
N  6.21
Since 0.000000621 is a number less than one, n is a negative integer. In this case, n  7.
Combining the above two steps:
0.000000621  6.21  107
1.23 (a) 15,200 (b) 0.0000000778
1.24 (a) Express 3.256  105 in nonscientific notation.
For the above number expressed in scientific notation, n  5. To convert t
