+
+The **`Math.Cbrt()`** [method](https://www.codecademy.com/resources/docs/c-sharp/methods) in C# returns the cube root of a given number. It handles positive, negative, and special floating-point values such as `NaN` and infinities.
+
+## Syntax
+
+```pseudo
+Math.Cbrt(double x)
+```
+
+**Parameters:**
+
+- `x` (double): The number whose cube root is to be calculated.
+
+**Return value:**
+
+The method will return a value of [type](https://www.codecademy.com/resources/docs/c-sharp/data-types) `double` unless the value passed is one of the following:
+
+- If `x` is `NaN`, the method will return `NaN`.
+- If `x` is `PositiveInfinity`, the method will return `PositiveInfinity`.
+- If `x` is `NegativeInfinity`, the method will return `NegativeInfinity`.
+- If `x` is negative, the method will return the real cube root (a negative number).
+
+## Example
+
+In this example, different numeric values are passed to `Math.Cbrt()` to calculate their cube roots:
+
+```cs
+using System;
+
+namespace MyCubeRoot {
+  public class Example {
+    public static void Main(string[] args) {
+      double a = Math.Cbrt(27);
+      double b = Math.Cbrt(-8);
+      double c = Math.Cbrt(1000);
+      double d = Math.Cbrt(0.125);
+
+      Console.WriteLine(a);
+      Console.WriteLine(b);
+      Console.WriteLine(c);
+      Console.WriteLine(d);
+    }
+  }
+}
+```
+
+This example results in the following output:
+
+```shell
+3.0000000000000004
+-2
+10
+0.49999999999999994
+```
+
+## Codebyte Example
+
+In this example, the cube root of 64 is calculated using `Math.Cbrt()` and printed to the console:
+
+```codebyte/csharp
+using System;
+
+public class Example {
+  public static void Main() {
+    double number = 64;
+    double cubeRoot = Math.Cbrt(number);
+
+    Console.WriteLine("The cube root of " + number + " is " + cubeRoot);
+  }
+}
+```
