Part 1 Review

In Normal Mode, write in Standard Notation and use the calculator.

1. 5.0 x 106 ______2. 1.2 x 101 ______3. 4.32 x 103 ______

In Sci Mode, write in Scientific Notation and use the calculator.

1. 36,500,000 ______2. 98,700 ______3. 7,510,000,000 ______

Part 2 Calculator Programming

As a class we will code (see attached coding directions) a graphing calculator program that evaluates the expression (2ab2)3 for the values you input. It expresses the result in scientific notation. If a = 9, b = 10, c = 0, the result is 5.832 x 109.

Pair up with a partner to help each other in the coding process.

Part 3 Editing the Program

Edit the program to evaluate each expression with your partner. Then evaluate a = 4. b = 6, and c = 8.

1. a2b3c4 ______2. (-a)4(3b)2(c)6 ______

3. (3a2bc)3 ______4. (-2b)2(4c)3 ______

** Extra:

What values of a, b, and c would make the exponent in scientific notation negative?
