Answer 2

1 + 3! + 5+ 7 + 11 = thirty

Step-by-step explanation:

3! + 3! + 3! + 3! + 3!      = 30 

3! + 1 + 3 + 9 + 11          = 30

1 + 5 + 7 + 3! + 11               = 30

3! + 3! + 3! + 11 + 1             = 30

3! + 3! + 11 + 5 + 1               = 30

           11+ 1 + 1 + 3! + 11              = 30

      15 + 3 + 3 + 3 + 3!              = 30

    13 + 1 + 1 + 9 + 3!            = 30

        133! + 3! + 3! + 3! + 3!      = 30 

  3! + 1 + 3 + 9 + 11          = 30

      1 + 5 + 7 + 3! + 11               = 30

            3! + 3! + 3! + 11 + 1             = 30

                3! + 3! + 11 + 5 + 1               = 30

           11+ 1 + 1 + 3! + 11              = 30

      15 + 3 + 3 + 3 + 3!              = 30

    13 + 1 + 1 + 9 + 3!            = 30

        13 + 1 + 3 + 7 + 3!            = 30

              13 + 5 + 3 + 3 + 3!            = 30 + 1 + 3 + 7 + 3!            = 30

              13 + 5 + 3 + 3 + 3!            = 30
