Answer:

The geometric mean of 27 and 8 is
6√(6) or about 14.697

Explanation:

The geometric mean is
( \prod_(i=1)^(n) x_(i))^{(1)/(n)}=\sqrt[n]{x_1x_2 \cdot\: \cdot \:\cdot x_n} where
n is the number of values and
x_i are the values to average. Thus, your geometric mean is
√(27*8)=√(216)=6√(6)\approx14.697

Answer:

x = 6√6

Explanation:

27/x = x/8

x² = 27 × 8

x = √(27 × 8)

x = √(9 × 4 × 6)

x = 3 × 2 × √6

x = 6√6
