This tool calculates the result of any base number raised to any power (exponent), including negative and fractional exponents.
Useful for algebra homework, scientific notation, and general exponent calculations.
Input the number being raised to a power.
Input the power to raise it to.
The calculation updates automatically.
It means taking the reciprocal of the base raised to the positive exponent: x^-n = 1/x^n.
Any nonzero number raised to the power of 0 equals 1.
It represents a root - x^(1/2) is the square root, x^(1/3) is the cube root, and so on.
Yes, negative bases work, though results can be positive or negative depending on whether the exponent is even or odd.
Yes, this calculator supports decimal exponents.
This is mathematically ambiguous/undefined in many contexts - conventions vary by field.
Related but different - scientific notation uses powers of 10 specifically to represent very large or small numbers.
No, calculations happen entirely in your browser.
Very large results may display in scientific notation due to JavaScript's number handling.
