Question

Find x^2 if x = whole root root 5 + 2 + whole root root 5 - 2/ whole root whole root 5 + 1.

Answer 1

its 5

Answer 2

Eh? Can you please explain with the steps.

Answer 3

Can you post a screenshot of the question?

Answer 4

How do I do that? I'm on my PC.

Answer 5

4+1=5

Answer 6

so its 5

Answer 7

What exactly did you do, Kidz_Wavy? How did you come to the conclusion of '4 + 1 = 5'?

Answer 8

lol 4 apples plus one apple=5

Answer 9

If you press "Print Screen" (located near the top right corner on a Windows keyboard) it will save an image of the screen in memory. Then you can paste the image in a free program such as Irfanview and do some editing to remove extraneous info on your screen that you don't want people to see and then upload the image here.

A curious child asked his mother: “Mommy, why are some of your hairs turning grey?”

The mother tried to use this occasion to teach her child: “It is because of you, dear. Every bad action of yours will turn one of my hairs grey!”

The child replied innocently: “Now I know why grandmother has only grey hairs on her head.”
and that is 5...

Answer 11

\[x = \sqrt{\sqrt{5} +2} + \sqrt{\sqrt{5} - 2} \div \sqrt{\sqrt{5 + 1}}\] find x^2

Answer 12

its 5

Answer 20

k im sorry but the answer is 5

Answer 21

\(
\Large
x = \frac{\sqrt{\sqrt{5} +2} + \sqrt{\sqrt{5} - 2}}{\sqrt{\sqrt{5 + 1}}} =
\frac{\sqrt{\sqrt{5} +2} + \sqrt{\sqrt{5} - 2}}{\sqrt{\sqrt{6}}}
\\ \Large

x^2 = \frac{(\sqrt{5} +2) ~+~ (\sqrt{5} - 2) ~+~
2\sqrt{\sqrt{5} +2} ~*~ \sqrt{\sqrt{5} -2}}{\sqrt{6}} = \frac{2\sqrt{5} ~+~
2\sqrt{5 -4}}{\sqrt{6}} \\ \Large

x^2 = \frac{2(\sqrt{5}+1)}{\sqrt{6}} = \frac{2\sqrt{6}(\sqrt{5}+1)}{6} =
\frac{\sqrt{6}}{3}(\sqrt{5}+1)

Answer 22

In the second line, the following algebraic identities were used:

\(\Large (a+b)^2 = a^2 + b^2 + 2ab \\ \Large
\sqrt{a}~*~\sqrt{b} = \sqrt{ab} \\ \Large
(a+b)(a-b) = a^2 - b^2
