Exp2 Negative Exponents
What would  10-2  equal?

Negative exponents  indicate a fraction or decimal

(a number between o and 1).  They are not negative

 by themselves.  For example 4-3 is the following.

  =  1

        100

 =  100
4 x 4 x 4
1

  =   1

          20

What would  2-3  equal?

Negative exponents  indicate a fraction or decimal (a

number between o and 1).  They are not negative by

themselves.  For example 4-3 is the following.

=     1

           6

 =    8

 
4 x 4 x 4

  =    ¼

What would  3-2  equal?

Negative exponents  indicate a fraction or decimal (a

number between o and 1).  They are not negative by

themselves.  For example 4-3 is the following.

 =     9

 =   -9

 
4 x 4 x 4

What would  -3-2  equal?

A negative sign in front of the exponent will reverse

 the direction of the answer.  For example -4-3 is as

follows:

 =    -9

 
-
4 x 4 x 4

What would  2x-4  equal?
 =

A number in front of the one in exponent form with

no sign between them is being multiplied by the

exponent.  If the exponent is a fraction, the number in

front goes over one to multiply it by the exponent.

42  x 43    =

Since 42  is 4 x 4 and 43  is 4 x 4 x 4 and 4 x 4 x 4 x

4 x 4 is 45  , 42  x 43  equals the following:

46
