Root Calculator

Calculate the square root, cube root, or any nth root of a number.

e.g., 2 for square root, 3 for cube root

Result
—
2 √ 16 = 4
使用方法
  1. Enter the Root Degree (n). For a standard square root, leave this as 2. For a cube root, change it to 3.
  2. Enter the Base Number (x) you want to find the root of.
  3. The calculator instantly evaluates the nth root of your number.

公式

Mathematical Definition:
If rn = x, then r is the nth root of x.

Fractional Exponent Rule:
n√x = x(1/n)

The Root Calculator makes it easy to extract not just square roots (which are built into basic calculators), but cube roots, 4th roots, and any arbitrary nth root. Finding the nth root is mathematically equivalent to raising a number to the power of 1/n.
