b. **Multiplication**.

xaxb = xa+b

Example.

2322 = 23+2 = 25 = 2 X 2 X 2 X 2 X 2 = 32

c. **Division**.

xa

---- = xa-b

xb

Example.

24

---- = 24-2 = 22 = 2 X 2 = 4

22

d. **Exponential Expressions Raised to a Power**.

(xa)b = xab

Example.

(22)3 = 2(2)(3) = 26 = 2 X 2 X 2 X 2 X 2 X 2 = 64

a. **Division. **Scientific notation uses the exponential method of expressing very

large and very small numbers in terms of an exponential expression. Utilizing this

method, numbers are expressed as a product of two numbers. The first number is

called the digit term and is a number greater than or equal to one but less than ten. The

second number of the product is called the exponential term and is written as a power of

ten.
