Final answer:
To simplify the expressions, we need to look for common factors in the terms under the square root. Option b) can be simplified further as 2√(3y) by dividing the constant term 4 by 2.
Step-by-step explanation:
To simplify the expressions, we need to look for common factors in the terms under the square root.
a) 2√(6y) cannot be simplified further because there are no common factors.
b) 4√(3y) can be simplified as 2√(3y) by dividing the constant term 4 by 2.
c) 2√(3y) is already simple and cannot be simplified further.
d) √(6y) cannot be simplified further because there are no common factors.
