## anonymous 5 years ago What is the geometric mean of 3 and 8?

1. amistre64

$geoMean(g_1,g_2,g_3,...,g_n)=\sqrt[n]{g_1*g_2*g_3*...*g_n}$

huh? im sorry. i dont understand that formula

geometric mean is the nth root after multiplying n numbers.. ex. if you have 2 numbers: a,b do sqrt(a*b) 3numbers? do cube root(a*b*c*) 4 numbers? 4th-root (a*b*c*d)
