A student is attempting to simplify the radical below. His mathematical work is also shown below. Which of the following statements applies to the sample mathematical work?
3.
Given
Step 1: I multiply the numerator by the denominator, so
Step 2: I distribute the products, which gives the expression
Step 3: I simplify the expression, and since 48 = 16.3 = 4 /3, then
= 3
A. The student failed to multiply the expression correctly in step 1.
B. The student failed to distribute the products correctly in step 2.
C. There is no error in the math, but the answer may be simplified further.
D There is no error in the math, and the answer cannot be simplified further.
