The expression 2x 2 x 2 x 2 can be expressed as 24
Base and Exponent
24 Exponent
Base
The expression 24
is called an exponential
notation or exponential form. The number 2 is called
the base and the number 4 is called the exponent.
8.
Base and Exponent
Theexponent tells how many times the base is used
as a factor. The base is the number used as a factor.
Thus, in the expression 24
, the exponent 4 tells that
the base 2 is used as factor 4 times
Therefore, we can say that 24
= 2 x 2 x 2 x 2 = 16

Read Factor Form Value
42 Four to the second
power or
four squared
4 x 4 16
23 Two to the third
power or two cubed
2 x 2 x 2 8
74 Seven to the fourth
power
7 x 7 x 7 x 7 2 401
Write True ifthe statement is correct and False if it is not
Exponent tells the number of times the base used as a factor.
