Question

Which expression is equivalent to sqrt 120x?

Answer 1

Answer:

a. $2\sqrt{30x}$

Step-by-step explanation:

We have been given a radical expression and we are asked to choose the correct option that is equivalent to our given expression.

$\sqrt{120x}$

Let us pull out perfect square from our radical expression.

We can rewrite our given expression as:

$\sqrt{4*30x}$

Since square root of 4 is 2, so we can pull out 2 from our radical expression.

$2\sqrt{30x}$

Therefore, the expression $2\sqrt{30x}$ is equivalent to our given expression and option a is the correct choice.  

Answer 2

The answer would be A) 2 sqrt 30x
