Never have heard of such a saying.
If you mean (Ab)2 then it is Ab, but if you mean Ab2 then it is square root (A)(b).
If you mean 2 times the square root of 169 then it is 26
% = the square root of Do you mean: %18 x 2 x %75 =%48? If so, then no, that's wrong.
The square root of the square root of 2
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.
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 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
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.
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
