Whoever it was who discovered that if you had a square whose sides were one unit long, the lengths of its diagonals were sqrt(2) - surds!
The square root of 2 plus the square root of 2 is equal to twice the square root of 2, therefore the correct answer is: 2(√2) or √8

2 is the same as the square root of 4. Square root of 4 multiplied by square root of 2 is equal to the square root of 8.
Surds are normally irrational numbers but they can be simplified for instance the square root of 12 can be expressed as 2 times the square root of 3

Surds are irrational square root numbers that cannot be solved but they can be simplified. For example the square root of 12 can be simplified to 2 times the square root of 3.
An example may help. If you have the fraction 1 / (2 + root(3)), where root() is the square root function, you multiply top and bottom by (2 - root(3)). If you multiply everything out, you will have no square root in the denominator, instead, you will have a square root in the numerator. If the denominator is only a root, eg root(3), you multiply top and bottom by root(3).

No; you can prove the square root of any positive number that's not a perfect square is irrational, using a similar method to showing the square root of 2 is irrational.
The square root of the square root of 2
2 square root 2
square root 2 times square root 3 times square root 8
The square root of 2 plus the square root of 2 is equal to twice the square root of 2, therefore the correct answer is: 2(√2) or √8

when u say have (Root)2 x (Root)3, u do (Root)2x3=(Root)6. so u just multiply the things inside the Root by each other inside a root, simples! =]
