EXPONENTS
Exponents is one of the basic unit
in geometry. They are used in
many formulas. So now, let us
have a look at them .
𝑥1
= 𝑥
This one is an easy one . For
example, if x=2 , 21
= 2.
𝑥 𝑜
= 1

This does not work with 0.
00
≠ 1
So, you knew what these two
equations meant, we will go to
the next ones .
𝑥2
= x *x
𝑥3
= 𝑥 ∗ 𝑥 ∗ 𝑥
𝑥 𝑛
= 𝑥 ∗ 𝑥 ∗. .∗ 𝑥

Sometimes ,something looks
easy ,but it is very hard .
For example , although the
equation given below looks
harmless , it is a tough one to
do.
68
= 1,679,616
For negative exponents we use
this important convention.

𝑥−𝑛
=
1
𝑥 𝑛
There is a special case which
you need to keep in your mind.
𝑥1 2⁄
= √ 𝑥
If x = 25,
251 2⁄
= √25 = 5
