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:
Expression with base^exponent:
25 = ? , 2-5 = ? , -25 = ? , -2-5 = ?
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
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
(an)m = an⋅m
Example: (23)4 = 2(3 ⋅ 4) = 212 = 4096
m√(an) = an/m
Example: 2√(26) = 2(6 / 2) = 23 = 8
a 0 = 1
Example: 40 = 1
