Solve (2x)^2 = 24 using square root property

Question

Hi, I keep trying to do this problem but getting the wrong answer. 

Answer 1

If I am reading the problem correctly, you need to square both the 2 and the x, which gives you:

 

4x^2 = 24, then you would divide both sides by 4. 

 

You get x^2 = 6. Take the square root of both sides and you get: x = sqrt(6) 

 

If the parenthesis are there for purposes of the squared function then you would get the following: 

 

x = 2sqrt(3)
