I dont really understand this :(

David estimated he had about 20 fish in his pond. a year later, there were about 1.5 times as many fish. the year after that, the number of fish increased by a factor of 1.5 again. the number of fish is modeled by f(x)=20(1.5)^x. create a question you could ask that could be answered only by graphing or using a logarithm.

What is the value of the expression i 0 × i 1 × i 2 × i 3 × i 4? 1 –1 i –i
