Question 1
A farmer stocked a newly dug pond with 1000 fish fingerlings. It is known that each year, the number of fish in the pond increases by $x$ times the initial number, and x is constant. By changing the farming techniques and fish feed, after two years, the number of fish in the pond is 36000. What is the annual growth rate of the fish population in the pond? Assume the growth rate each year is constant.
