Two.
Root 11 plus root 11 can be expressed as ( \sqrt{11} + \sqrt{11} ), which simplifies to ( 2\sqrt{11} ). This means you have two times the square root of 11.
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.
