THe answer is #=sqrt44-1#

As the equation of the sphere is #(x-2)^2+(y-2)^2+(z-6)^2=1#

So the center of the sphere is at #(2,2,6)# and the radius is #r=1#

The distance from the origin to the center of the sphere is
#=sqrt(2^2+2^2+6^2)=sqrt44#

To find the shortest distance, we have to remove the radius
#sqrt44-1#
