The number of trees left after 11 years will be 0.
To find the number of trees that will be left after 11 years, we need to calculate the number of trees that will die each year and subtract that from the initial number of trees. Given that (1)/(4) of the trees die per year, we can calculate how many trees will be left after 11 years as follows:
Number of trees left = Initial number of trees - (Number of trees that die each year x Number of years)
Number of trees left = 800 - (800 x (1)/(4) x 11)
Number of trees left = 800 - 2200
Number of trees left = -1400
Since the number of trees cannot be negative, the answer is 0. There will be no trees left after 11 years.
