About the Exponent Calculator
This calculator computes x^y (x raised to the power of y) and also displays the common shortcuts: square (x²), cube (x³), square root (√x), and cube root (∛x). Calculations run locally in your browser.
Formulas
- Power:
x^y— repeated multiplication when y is a positive integer; generalized for any real y by JavaScript'sMath.pow. - Square:
x² = x × x - Cube:
x³ = x × x × x - Square root:
√x = x^(1/2) - Cube root:
∛x = x^(1/3)
How to use
- Enter the base x.
- Enter the exponent y.
- Click Calculate. The result section shows
x^yalong with square, cube, square root and cube root of x.
Frequently asked questions
What is 0 to the power 0? Mathematically debated. JavaScript defines Math.pow(0, 0) as 1; this calculator follows that convention.
What about negative base with fractional exponent? Many such cases produce complex numbers and are not representable as a real number. The calculator will report NaN in those cases.
How large can results be? JavaScript numbers max out around 1.8 × 10^308. Larger results will display as Infinity.
Can y be negative? Yes. x^-1 = 1/x, x^-2 = 1/x², and so on. The calculator supports negative exponents directly.
