Expressing Numbers in Terms of Scientific Notation

b. Multiplication.

xaxb = xa+b

Example.

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

c. Division.

---- = xa-b

Example.

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

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

1-21. EXPRESSING NUMBERS IN TERMS OF SCIENTIFIC NOTATION

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.
