1. Mark what is covered and what is not covered in Chapter 8:
2. Write a method named ex24 for computing the cubic root of the sum of two given real numbers x and y. Hint: a cubic root of a number z is equal to the number z raised to the power 1/3.
3. Call your method ex24 in the main method to compute the cubic root of a + b, where a = 3.0 and b = 5.0. (You do not need to write the entire main method, just the part that assigns values to a and b and calls your method.)
4. Trace, step by step, how the computer will perform the needed computations, and check that the result is indeed correct.
