root 2 + root 2 = 2 root 2 or root 8
To find this answer this is what you do.
To add radicals the numbers under the radical must be the same (in this case they are both 2 so this step is already done)
Then even though you cannot see it there is a 1 in front of both of these radicals, so that means you have to add the 1's together.
1 root 2 + 1 root 2 = 2 root 2
Also the numbers under the radical do not change in this process.

(7*sqrt(2))/2 (Seven time the square root of 2, divided by two)
8
2 cube root 24 plus 3 cube root 81 is 18.7492444
5 root 2
3.414213562
The square root of four is two. Therefore, 20.84 plus 2 is 22.84.
five
12.937254
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.
The question is: What is (root 3) + (2 x root 2)? I presume it means "square root". The answer is: 4.560478 approximately.
Two times the square root of three plus five times the square root of three plus four times the square root of three equals eleven times the square root of three.
plus (+) 70 and minus (-) 70
No. For example, the square root of two plus (minus the square root of two) = 0, which is not an irrational number.
The answer is 620. Simply add the numbers together like you would for two plus two. To check your work, a calculator is the best option.
They are minus 17 and plus 17
