Answer:

Step-by-step explanation:

a) 1242 = 2 * 621

           = 2 * 3 * 207

           =  2 * 3 * 3 * 69

           =  2 * 3 * 3 * 3 * 23

           =2^1 * 3^3 * 23^1

b) 811 = 1 * 811

         = 1^1 * 811^1                    ( 811 is a prime factor )

c) 9600 = 2 * 4800

              = 2 * 2 * 2400

              =  2 * 2 * 2 * 1200

             =  2 *2 * 2 * 2 *600

             =    2 * 2 * 2 * 2 * 2 * 300

             = 2 * 2 * 2 * 2 * 2 *2 * 150

             = 2 * 2 * 2 * 2 * 2 * 2 *2 * 75

            =  2 * 2 * 2 * 2 * 2 * 2 *2 * 3 * 25

            =  2 * 2 * 2 * 2 * 2 * 2 *2 * 3 * 5* 5

           = 2^7 * 3^1 * 5^2
