Formula Explanation

The formula used in the calculator is:

n√x = y


  • n is the index of the root
  • x is the number under the radical
  • y is the result of the calculation


Suppose we want to find the cube root of 27. We can use the Radicals and Roots Calculator to find the answer.

  1. Enter the index of the root, which is 3.
  2. Enter the number under the radical, which is 27.
  3. Click the "Calculate" button.
  4. The result, which is the cube root of 27, is displayed as 3.

Real-Life Applications

The Radicals and Roots Calculator is useful in various fields such as engineering, physics, and chemistry. It is used to simplify and solve equations involving roots and radicals. For example, in electronics, the calculator is used to calculate the root mean square (RMS) value of a waveform. In architecture, the calculator can be used to determine the length of a diagonal line in a rectangular floor plan.

Example 2

Radicals and roots are used in many fields, such as construction and engineering. For instance, architects and engineers may use square roots to calculate the dimensions of a room or building. In construction, square roots can be used to determine the angles for cutting rafters or stairs.

For example, a construction worker needs to find the length of a diagonal of a square room with sides of length 6 feet. Using the Pythagorean theorem, we can find the diagonal:

diagonal = √(62 + 62) = √72 ≈ 8.49 feet
