We know in these kind of triangles that have a 90 degrees angle, we can do:

so the first question:

and then:

so , when you want to rationalize , usually you must multiply the irrational factor as 1:

so , now multiply:

in the next question,we know negative numbers in radical don't have any solution so 2 is correct,
Start off with (x+1)(x-1). If x is 5 for example, use 4 and 6. For any odd number x, there are two even numbers next to it on the number line. One of these will be at least a multiple of 2 and one at least a multiple of 4. If you go to a number line, you see that in every group of 4 natural numbers has 2 odds and 2 evens. These evens include that multiple of 4 (or a greater power of 2) and that multiple of 2 (or greater power of 2).
