How do you get the square root signs?
The square root of something squared is that thing
The first part becomes the square root of 12 - square root of three.
As 12 = 4 x 3 the square root of 12 is the root of 4 x root of 3
= 2 root 3 and 2 root 3 - root 3 = root 3.
the second part
root 27 = root 9 x root 3 or 3 root 3
root 8 becomes root 4 x root 2 or 2 root 2
Sorry this is too difficult to answer writing root all the time. You should be able to see where I am going.
Sorry, I made a mistake with where the brackets are but the rest is correct.
