+    Calculate a custom equation based on the parameters provided.
+
+    This function computes the result of the equation:
+    (x^a + y^b) / c, where:
+    - `x` and `y` are the bases for exponentiation.
+    - `a` and `b` are the exponents for `x` and `y`, respectively.
+    - `c` serves as the divisor, which cannot be zero.
+
+    :param x:
+        The base for exponentiation (positional only). Default is 0.
+
+    :param y:
+        The base for exponentiation (positional only). Default is 0.
+
+    :param a:
+        The exponent for `x` (positional or keyword). Default is 1.
+        This defines the power to which `x` is raised.
+
+    :param b:
+        The exponent for `y` (positional or keyword). Default is 1.
+        This defines the power to which `y` is raised.
+
+    :param c:
+        A keyword-only parameter representing the divisor. Default is 1.
+        If set to zero, a division by zero exception is raised.
+
+    :raises ValueError:
+        If `c` is zero, a `ValueError` is raised indicating that division by zero
+        is not allowed.
+
+    :returns:
+        The result of the equation (x^a + y^b) / c.
+        This will return a float value representing the computed result.

+
+    #>>> custom_equation(2, 3, a=2, b=2, c=1)
+    13.0
