A test tube initially holds 25 bacteria. The population of bacteria in the test tube doubles each hour. Without making a graph, determine how many hours it will take for the population of bacteria in the test tube to reach 800. Explain how you solved this problem.
25*2^X=800 2^X=32 If you put a radical sign over each side, the index for 2^X would have to be 5 for X to disappear and the equation to be true. In other words, ({5}(√2^X)=({5}(√32)), which means that It will take 5 hours
