A student's work to simplify a radical is shown below. Select the statement which best applies to the sample mathematical work.
54 =27 2
27 2 = 332
Thus, 54 = 3/2
A. The equality 54 = 27.2 is incorrect or invalid.
B. Removing the 27 from under the radical in the second step is incorrect or invalid.
C. The work shown above is correct, however 3/2 may be simplified further.
D. The work shown above is correct, and 32 may not be simplified further.
