Power and root calculator

Calculate powers (base raised to an exponent) and roots (square and nth).

Power (base^exponent)

1,024

Square root of base1.414214

Root of index "exponent" of base1.071773

Even-index roots require a non-negative base.

How the calculation works

Power: base^exponent multiplies the base by itself "exponent" times. The root is the inverse: the nth root is base^(1/n).

What is a number to the power of zero?

Any number (except 0) raised to 0 equals 1.

Solve quadratic equations (ax² + bx + c = 0) with the delta and roots step by step.
