Discuss any difficulties you might have with grasping the concepts used in radical expressions.?

A square root of a number is one number that when multiplied by itself, gives you the number you started with for example 9... what number multiplied by itself will equal 9? 3, so 3 is the square root of 9... then do the same with cube roots and stuff... and just explain that the radical sign is used to represent "square root" so a radical around 9 is the square root of 9 is not equal to 9.
