Exponents is important topic in algebra, Let’s understand exponents and each rule in detail, and see some examples.
What is an exponent
Exponents are the multiplication of the same thing by itself. An expression that represents repeated multiplication of the same factor is called a power.
Example: 4^{3} = 4 X 4 X 4 = 64
In words: 4^{3} could be called “4 to the third power”, “4 to the power 3” or simply “4 cubed”
a^{n} = a × a × … × a
n times
a is the base and n is the exponent.
Rule name 
Rule 
Example 
Product rules  a^{ n} ⋅ a^{ m} = a^{ n+m}  2^{3} ⋅ 2^{4} = 2^{3+4} = 128 
a^{ n} ⋅ b^{ n} = (a ⋅ b)^{ n}  3^{2} ⋅ 4^{2} = (3⋅4)^{2} = 144  
Quotient rules  a^{ n} / a^{ m} = a^{ n}^{–m}  2^{5} / 2^{3} = 2^{53} = 4 
a^{ n} / b^{ n} = (a / b)^{ n}  4^{3} / 2^{3} = (4/2)^{3} = 8  
Power rules  (b^{n})^{m} = b^{n⋅m}  (2^{3})^{2} = 2^{3⋅2} = 64 
_{b}n^{m} _{= b}(n^{m}) 
_{2}3^{2} _{= 2}(3^{2})_{= 512} 

^{m}√(b^{n}) = b ^{n/m} 
^{2}√(2^{6}) = 2^{6/2} = 8  
b^{1/n} = ^{n}√b  8^{1/3} = ^{3}√8 = 2  
Negative exponents  b^{n} = 1 / b^{n}  2^{3} = 1/2^{3} = 0.125 
Zero rules  b^{0} = 1  5^{0} = 1 
0^{n} = 0 , for n>0  0^{5} = 0  
One rules  b^{1} = b  5^{1} = 5 
1^{n} = 1  1^{5} = 1  
Minus one rule  (1)^{n} = 1 , n is even (1)^{n} = 1 , n is odd 
(1)^{5} = 1
