Where x
x
represents an unknown number. From the last line, we can find height of the tree after a certain number of years by taking x
x
equal to that number. For example, we simply let x=15
x
=
15

. Thus, the value of x
x
depends on our choice. We can give x

any value or number we want. In other words, the value of x
x
is not fixed, it varies from one situation to the other. Therefore, we call x
x
a variable whereas 10

is a fixed number whole value does not change. So 10
10
therefore is called a constant.
