A student's work to simplify and combine radicals is shown below. Select the statement that best applies to the sample mathematical work.
Given 3 V5 +2.127.1 observe that 27 = V0 3 and that 9 is a perfect square, so I simplify to get the expression to
315-18.15.1 can then combine these terms to get 213, which is my answer.
The student erroneously attempted to combine terms with different indices.
B. The student did not properly simplify the radicals.
C. The student did not property. combine the radical terms.
D. The work shown above is correct and there is no error.
