Exponents and Powers
The Exponential form, also known as the exponents, indicates the number of times the number is to be multiplied. For example 105
Here, the base is 10, the exponent is 5, and the whole number is the power. We pronounce it as 10 raised to the power 5. The exponent can be either positive or negative.

Powers with Negative Exponents
The exponents can also be negative and can be converted to a positive number using the following method.
$10^{-4}=\frac{1}{10^4}$
This indicates that for every non-zero negative integers,
$a^{-m}=\frac{1}{a^m}$
where m is the positive integer and am is the multiplicative inverse of a-m.
2. Law of Exponents
If we have bases a and b, and exponents m and n, then
-
aman=am+n
-
(am)n
-
$\frac{a^m}{a^n}=a^{m-n}$
-
ambm = (ab)m
-
a0 = 1
-
a1 = a
