If this is 1%2F%282sqrt%2818%29%29+-+3%2Fsqrt%282%29+-+9sqrt%2850%29, as the other person suggests, the correct answer is NOT - 18, as he/she states.
The correct, simplified answer would be: %28-+1671sqrt%282%29%29%2F36
However, if it's %281%2F2%29sqrt%2818%29+-+3%2Fsqrt%282%29+-+9sqrt%2850%29, correct SIMPLIFICATION is
       as follows: %281%2F2%29sqrt%289+%2A+2%29+-+3%2Fsqrt%282%29+-+9sqrt%2825%2A2%29
                          %281%2F2%29%283%29sqrt%282%29+-+3%2Fsqrt%282%29+-+9%285%29sqrt%282%29
