Math.Sqrt

XAML:

<Grid>
    <Button Content="&#8730;" HorizontalAlignment="Left" Margin="145,10,0,0" VerticalAlignment="Top" Width="75" 
            Click="OnSquareRootClick"/>
    <TextBox x:Name="txtNumber" HorizontalAlignment="Left" Height="23" Margin="10,10,0,0" Text="" VerticalAlignment="Top" Width="120"/>
    <TextBox x:Name="txtResult" HorizontalAlignment="Left" Height="23" Margin="240,10,0,0" Text="" VerticalAlignment="Top" Width="120"/>
</Grid>

Code Behind:

 private void OnSquareRootClick(object sender, RoutedEventArgs e)
    {
        double number;
        var isDouble = double.TryParse(this.txtNumber.Text, out number);
        if (isDouble)
        {
            this.txtResult.Text =
                string.Format(
                    "{0}{1} = {2}", 
                    "\u221A", 
                    this.txtNumber.Text, 
                    Math.Round(Math.Sqrt(number), 2));
        }
    }
