 So, basically Mathematica gives me this answer:1/5 (3 + 6 Sqrt[3/5] + 3 Sqrt[6/5] + 3 Sqrt[7/5] + Sqrt[2] + Sqrt[11/   5] + Sqrt[13/5] + Sqrt[14/5] + Sqrt[3] + Sqrt[17/5] + Sqrt[19/5] +    Sqrt[21/5] + Sqrt[22/5] + Sqrt[23/5] + 16/Sqrt[5] + Sqrt[5] + Sqrt[   26/5] + Sqrt[29/5] + Sqrt[6] + Sqrt[31/5] + Sqrt[33/5] + Sqrt[34/   5] + Sqrt[7] + Sqrt[37/5] + Sqrt[38/5] + Sqrt[39/5] + 2 Sqrt[10])I need this as just one number. How can I make Mathematica calculate this?

 You may also specify the number of decimal places you would like the exact numerical solution to be approximated to by calling:N[Expression,3]Where 3 indicates that you will receive three decimal places.

 Just use this command;N[Expression] or Expression//N
