I am having trouble understanding what to do and how to do it could someone PLEASE help me understand this?! Part A: Use the properties of exponents to explain why 18 raised to the power of 1 over 5 is called the fifth root of 18. Part B: The length of a rectangle is 2 units and its width is square root of 2 unit. Is the area of the rectangle rational or irrational? Justify your answer.
