$\sqrt{ x^{2} +5} + \sqrt{ ( x^{2} +5)^{3} } = (\sqrt{ x^{2} +5})(1+ \sqrt{ ( x^{2} +5)^{2} } ) \\ =(\sqrt{ x^{2} +5})(1+ x^{2} +5 )=(\sqrt{ x^{2} +5})(x^{2}+6)$

Let x = the 2nd number

Let x + 8 = the first number

Let 4x = the third number

x + x + 8 + 4x = 122

6x + 8 = 122

6x = 114

x = 19

x + 8 = 19 + 8 = 27

4x = 4(19) = 76

Step-by-step explanation:

The sum of three numbers is 122 . The first number is 8 more than the second. The third number is 4 times the second
