Enter any number and see every common root and power of it in a single table: square root, cube root, fourth and fifth roots, its square and its cube.
The square root of a number is the value that, multiplied by itself, gives the number back — 12 × 12 = 144, so the square root of 144 is 12.
No real number multiplied by itself gives a negative result, so negative numbers have no real square root. This tool covers the standard set of roots used in school and everyday work.
The 4th root is the square root of the square root; higher roots appear in geometry, engineering and growth calculations.
