it means you need to do B to the power m, then take the nth root of your answer. eg 9 to the power 3/2, means you do 9 cubed and then square root your answer. in this case, its easier to do the square root first and then cube your answer as the square root of 9 is 3, and 3 cubed is 27. therefore 3 to the power 3/2 equals 27
