A student is attempting to simplify the radical below. Her mathematical work is also shown below. Which of the
following statements applies to the sample mathematical work?
45
Given:
V3+4
Step 1: I first multiply out the radical in the denominator, so I get the expression 4V2 V3-4.
√3+4 √3-4
476-1672
Step 2: I distribute the products, which gives the expression
19 - 4/3 + 4/3 - 16
476-1673
Step 3: I simplify the expression and get,
-13
Step 4: 1 multiply the entire expression by and get,
-416 +1672
Step 5: Since the expression cannot be simplified, I have 1612 - 416
13
as a final answer.
