With difficulty!
There is far too little here to go on, and this seems an odd question
unless it is homework (why dictate a problem-strewn method of solution
if this is a real problem?)
The real issue is how to bootstrap nonlinear regression, and you will
find that discussed in all good books on the subject, such as Venables &
Ripley and Davison & Hinkley. It is not trivial and the solutions are
not altogether satisfactory ....
