Title: Calculate Nth roots in C#

To calculate Nth roots, you can simply use the formula:

    root = K1/N

The example program uses the following code to calculate roots.

// Calculate the root. private void btnCalculate_Click(object sender, EventArgs e) { double number = double.Parse(txtNumber.Text); double root = double.Parse(txtRoot.Text); // Calculate the root. double result = Math.Pow(number, 1 / root); txtResult.Text = result.ToString(); // Check the result. double check = Math.Pow(result, root); txtCheck.Text = check.ToString(); }

The code parses the number and the root. It uses Math.Pow to raise the number to the 1/root power and displays the result. To check the result, the code then raises the result to the root power and displays the new result.
