`11^x/11^3=11^2`

The greatest value of x satisfying the equation |(2^11-x,-2^12,2^11),(-2^12,2^11-x,2^11),(2^11,2^11,-2^12-x)|=0 is

2/11+3/11+8/11

5/11+3/11+2/11

7/11+(-3)/11

5/11+8/11-2/11

If int_(0)^(11) (11^(x))/(11^([x]))dx = k/(log11) , (where [] denotes greatest integer function) then value of k is
