Answer:
The correct answer is: Option D) 5
Step-by-step explanation:
Given equation is:

In order to find that which values of x makes the equation true, we have to put each value of x in the equation. When both sides of equations will be equal, that value of x will be true for the equation.
Putting x = 2

Putting x = 3

Putting x=4

Putting x = 5

The equation is true for x = 5
Hence,
The correct answer is: Option D) 5
Answer:

Step-by-step explanation:
When taking a square root and making it a radical, we need to list out it's factors and find which one we can take the square root of.
The factors of 40 are:
1, 2, 4, 5, 8, 10, 20, 40.
Out of these, we need to look for one that we can find the square root of.
We know that the square root of 4 is 2.
Therefore, we can make
into
.
The square root of 4 is 2. Therefore, we can put that outside the radical.
.
