need some help, whats a geometric mean

OpenStudy (ivettef365):

it is the nth root of the product of n numbers

OpenStudy (ivettef365):

if you have 2, 8 and 4 then cubic root 2 x 8 x 4 = 4 cubic root because there are 3 numbers

OpenStudy (jack1):

if it's only 2 numbere ( a and b) geometric mean is sqrt of (a times b)

OpenStudy (anonymous):

is it the same thing when the is asking for the geometric mean "between" 2 numbers?

OpenStudy (anonymous):

the Question*

OpenStudy (jack1):

yep

OpenStudy (ivettef365):

right

OpenStudy (jack1):

its just like its asking for a certain relationship "between" 2 numbers

OpenStudy (anonymous):

gotcha but when i multiplied a*b then squared the result of a*b my answer was nt any of the choices tht was given so what did i do wrong?

OpenStudy (jack1):

... from the way you described it... nothing

OpenStudy (jack1):

what are your numbers?

OpenStudy (anonymous):

6 and 8

OpenStudy (jack1):

dammit, sorry, u need to square root, not square

OpenStudy (jack1):

\[\sqrt{ab}\]

OpenStudy (jack1):

sqrt is just shorthand for square root

OpenStudy (anonymous):

nonono thts what i did, i found the square root of 6*8 and i got this string of retarted numbers.. O.O

OpenStudy (jack1):

6*8 = 48 sqrt 48 = 6.93

OpenStudy (jack1):

what did u get?

OpenStudy (anonymous):

my choices are a) 7 b) c) 14 d) 48

OpenStudy (jack1):

whats b...?

OpenStudy (jack1):

and i guess if you're rounding 6.93 ~~~ 7

OpenStudy (anonymous):

oops.. it was 4sqrt3 but it had the square root symbol after the 4

OpenStudy (jack1):

6.928 = 4* sqrt 3 = sqrt 48

OpenStudy (jack1):

id def go b

OpenStudy (anonymous):

alright thanks i appreciate it. ill be back later for other q's, goin for lunch

OpenStudy (jack1):
