Section 1.3 Homework Hints

Problems 7-10
See Example 2; scientific notation is to write the number as a number between 1 and 10 times a power of ten, and floating-point notations refers to calculator notation. The form given in the book is called fixed point notation. Rewrite each number with a decimal point following the first digit, and then multiply by an appropriate power of ten.

For example, Problem 7a: 3,200 = 3.200 * 10^3.

Don't forget floating-point notation, as well: 3.2 03

Hint for Problem 10a; look at Table 1.1.
