        {
            // for loop calculation
            int total;
            for (int i = 1; i < power; i++)
                total = power * baseNum;
            return  baseNum * +baseNum * +baseNum * +power;
        }

        //this closes app
        private void exitToolStripMenuItem_Click(object sender, EventArgs e)

Solution 1

How about something like:

lblresult.Text = baseNum.ToString() + "^" + power.ToString() + "=" + result.ToString()

Or do you need something fancier? I'd probably use a string builder or something else, but you should be able to get the idea.

Or do you mean something totally different?

C#

try
            {
                // Declare variables
                int baseNum = int.Parse(basetxt.Text);
                int power = int.Parse(powertxt.Text);

                // Declare variable to hold value
                int result = CalculatePower(baseNum, power);

                // Send resul
                lblresult.Text = string.Format("{0:.###}^{1:.###}={2:.####}", baseNum, power, result);
            }
            catch
            {
                // Display message

            }
         }
        private int CalculatePower(int baseNum, int power)
        {
            // for loop calculation
            int total;
            for (int i = 1; i < power; i++)
                total = power * baseNum;
            return  baseNum * +baseNum * +baseNum * +power;
        }

        //this closes app
        private void exitToolStripMenuItem_Click(object sender, EventArgs e)

Solution 2

Sometimes, if the given number is having decimals, the result may have several decimals, I think the following can be used in such case

C#

lblresult.Text = string.Format("{0:.000}^{1:.000}={2:.0000}",baseNum,power,result);

If zero is not required to be printed for all decimal places then

C#

lblresult.Text = string.Format("{0:.###}^{1:.###}={2:.####}",baseNum,power,result);
