Here is the definition for System.Math.Pow

public static double Pow( // https://msdn.microsoft.com/en-us/library/system.math.pow(v=vs.110).aspx
    double x,
    double y
)

You could piggy back on the above; keep in mind that exceptions are possible.

public static decimal DecimalPower(decimal x,  decimal y)
{
    Double X = (double)x;
    Double Y = (double)y;
    return (decimal)System.Math.Pow(X, Y);
}

edit:      example

void Main()
{
    Decimal p = (Decimal)Math.Sqrt(2.0);
    Console.WriteLine(p);
    Decimal y = 2.0M;
    Console.WriteLine(DecimalPower(p,y));
}

output:

1.4142135623731
2.00000000000001

end edit.

But I don't find how do it...

1) What is it that you do not know how to do?

2) Do you know how to write a method that returns a result?

3) Can you write a method that adds two numbers?

4) Is this an exercise from your text book or an assignment from your tutor?

5) Have you done the previous exercises?
