Question : 60 of 211

Marks: +1, -0

The geometric mean of 3,7,11,15,24,28,30,0 is

Solution:

Concept:

The geometric mean of a set of numbers is the

n

th root of their product; if any value is zero, the product is zero, hence the geometric mean is zero.

Explanation:

Given numbers:

3, 7, 11, 15, 24, 28, 30, 0

The product includes a factor

0

, so the entire product is

0

The geometric mean is

\sqrt[8]{0} = 0

Answer:

0
