Which expression is equivalent to ^
Firdavs [7]

Answer:

The first answer choice is the correct one.

Step-by-step explanation:

√(120x) can be rewritten as √(4*30*x).  I have chosen these factors because 4 is a perfect square.  This √(4*30*x) can be simplified further, leading to

√4 * √(30x), which in turn equals 2√(30x),

The correct answer is the first one of the four given.
