Question

what is the geometric mean of 3 and 7?

Answer 1

To find the mean of something, you add the terms and then divide by the amount of them. So, they equal 10 and there are two of them. 10/2 = 5. The mean should be 5.

Answer 2

Square root of product

Answer 3

I thought I multiply the two and find the square root?

Answer 4

I repeat Square root of product

Answer 5

Don't listen to me... O_O I may very well be wrong.

Answer 6

so I should square root 21?

Answer 7

Yes

Answer 8

but that just gets a weird number

Answer 9

If it was 3 numbers, then cube root of 3 multiplied together....

Answer 10

ah i see

Answer 11

It's just a different kind of average....

Answer 12

So would I do something like 2*square root of the product?

Answer 13

Nope, just sqrt 21, that's the GM

Answer 14

so I just leave it at square root 21?

Answer 15

Yup

Answer 16

why's that?

Answer 17

What do you mean?

Answer 18

why do i leave it at \[\sqrt{21}\] ?

Answer 19

Is there something wrong with sqrt 21 ?

Answer 20

don't I have to actually sqaure root it and make it
X *\[\sqrt{X}\]

Answer 21

or something like that?

Answer 22

I don't understand, the square root of 21 is roughly 4.5825, unless you are asked to give a decimal approximation, just leave it as sqrt 21

Answer 23

oh ok thanks

Answer 24

ur welcome
