Question

What is the geometric pair of radical 8 and radical 2?

Answer 1

Does "geometric pair" mean "geometric mean?" The geometric mean would be 4 but I don't know if that's what you are seeking.

Answer 2

Yes, geometric mean. Sorry. Haha.
Thank you!

Answer 3

Okay. x is the geometric mean between two numbers means, in this case, that radical 8 is to x as x is to radical 2.

√ 8 / x = x / √ 2

x^2 = √ 16

x = 4 Note: x also = -4 but by definition, geometric mean is not negative.

Answer 4

Thanks! You can explain it better than my teacher. Haha.

Answer 5

Thanks for the compliment (and the medal).
