It is given that x=3+31/2
Therefore the value of x is 37/2
The expression x2 +9/x2 can be written as 2x +9/2x Or 4x^2+9/2x
Substituting the value of x we get 4*(37/2) ^2 +9 / 2*37/2 Or, 37*37+9/37 Or, 1378/37 Or, 37.24
Therefore the value is 37.24
Therefore the value of x is 37/2
The expression x2 +9/x2 can be written as 2x +9/2x Or 4x^2+9/2x
Substituting the value of x we get 4*(37/2) ^2 +9 / 2*37/2 Or, 37*37+9/37 Or, 1378/37 Or, 37.24
Therefore the value is 37.24
