One third
[ 2 minus square root of 5 ] is the only one.
You can. Just add the numbers together, and find their square root. One plus three is four; the square root of the sum is two.
Nothing. You cannot have a square root of a negative number. The square root of negative one is called i, but i is an imaginary number. It does not exist and does not follow the properties of real numbers. (For example, if a and b are positive, then the square root of a times the square root of b is the square root of ab. But the square root of -7 is not the square root of 7 times i.)
if x^2 = 49, then the square root property says you can take the square root of both sides as long as you make one a plus-minus. x^2 = 49, which means square root of x^2 = plus minus the square root of 49 the square root of 49 is 7, so +- 7. We get: x = plus/minus 7 (this means either positive 7 or negative 7)
One third
square root of 4x is 2 times square root of x, so answer is square root of x times 3 since it is 2 square roots of x plus one of them

This one's ugly.(5 times the square root of 23 minus 4it)(5 times the square root of 23 plus 4it)where i is the square root of negative one.
It is √3/3 or "root three over three."√1/√3 ("the square root of one-third")1/√3 ("one over root three") (The square root of one is one.)√3/3 ("root three over three") (Rationalize the denominator.)
Find the square root of one side squared plus the second side squared.
[ 2 minus square root of 5 ] is the only one.
You can. Just add the numbers together, and find their square root. One plus three is four; the square root of the sum is two.
If this is supposed to be a riddle, it's not a very good one. The square root of the number whose square root is two is, obviously, two.
Square root of one is one, so four times this is four, add 9 is 13

In one bracket, write 16 times the square root of 2 minus 3x. In the other one, write 16 times the square root of 2 plus 3x.
