By root, I think you mean square root. The square root of 2 is approx. 1.414. The square root of 9 = 3, so this goes exactly at 3 on the number line. Square root 2 will be less than 1/2 way between 1 and 2 on the number line.

If you mean the square root of two, then the answer is irrational. However, it is known as Pythagoras' constant. The square root of 2, in geometrical terms, is the diagonal of a square.

(8)/(square root of 2) = [(4) x 2)]/(square root of 2) = [4 x square root of 2 x square root of 2]/(square root or 2) = [4 x square root of 2] = 4 x 1.414 = 5.656

Take the square root of the square root of the number (that is the fourth root of the number), for example: √√16 = √(√16) = √4 = 2 24 = 16 ⇒ 2 is the fourth root of 16.

Root 64 is 8, if by root you mean the square root. Then the problem become -square root 84(6+8) which is the - square root of 84(14) But square root of 84 is 2(square root of 21) so the final answer comes from -2(square root 21)x14 which is -28square root (21)

If you mean 84 squared then it is 84*84 = 7056 If you mean the square root of 84 then it is 2 times the square root of 21 which is an irrational number

No, divisors are integers and square root are often not. So the square root of 4, for example, is 2 and yes 2 is a divisor of 4. But the square root of 5 is not a divisor of 5 because it is not an integer. So sometimes square root are divisors and more often they are not.
