Exponents Calculator

Exponents calculator with negative numbers and steps.

 
 

* Use e for scientific notation. E.g: 5e3, 4e-8, 1.45e12

** To find the exponent from the base and the exponentation result, use logarithm calculator:

Exponents laws and rules

The exponent formula is:

a n = a×a×...×a

n times

The base a is raised to the power of n, is equal to n times multiplication of a.

For example:

25 = 2×2×2×2×2 = 32

Multiplying exponents

an am = an+m

Example: 23 ⋅ 24 = 2(3+4) = 27 = 128

 

an bn = (a b) n

Example: 32 ⋅ 42 = (3⋅4)2 = 122 = 144

 

Dividing exponents
an am
= a n-m
Example:
25 23
= 2 (5-3) = 2 2 = 4

 

an bn
= ( a/ b) n
Example:
82 22
= (8/2) 2 = 4 2 = 16

 

Power of exponent

(an)m = anm

Example: (23)4 = 2(3 ⋅ 4) = 212 = 4096

 

Radical of exponent

m√(an) = an/m

Example: 2√(26) = 2(6 / 2) = 23 = 8

 

Negative exponent
a -n =
1 a n
Example: 2 -3 =
1 23
=
1 8
= 0.125

 

Zero exponent

a 0 = 1

Example: 40 = 1
