What This Calculator Does
The Exponent & Root Calculator computes powers, square roots, cube roots, and arbitrary nth roots in one step. Exponents and roots are inverse operations.
How It Works
Enter a base and exponent. The calculator computes the power and the corresponding root. For example, base 27 and exponent 3 gives 27^3 = 19,683, with cube root = 3.
Example
8^2 = 64. Cube root of 64 = 4.
Formula
x^n and nth-root(x)Reading the Results
Power
The base raised to the given exponent.
nth Root
The root that when raised to the exponent gives back the base.
Frequently Asked Questions
What is a negative exponent?
A negative exponent means the reciprocal: x^(-n) = 1/(x^n).
What is a fractional exponent?
A fractional exponent is a root: x^(1/n) is the nth root of x.
How do I calculate 2 to the power of 10?
2^10 = 1024. This is a common value in computing (1 kilobyte = 1024 bytes).
