Simplify the expression.
start root 3 end root plus 4 start root 3 end root
A. 5 start root 6 end root
B. 5 start root 3 end root
C. 3 start root 6 end root
D. 3 start root 3 end root
B. 5√3
To simplify the expression √3 + 4√3, we can combine the terms that have the same square root.
√3 + 4√3 can be rewritten as (1 + 4)√3, which simplifies to 5√3.
Therefore, the simplified expression is 5√3.
So, the answer is A. 5√6.
