Find the geometric mean of each pair of numbers.
1/12, 1/18
I understand to multiply 1/12 * 1/18 and take the sqrt of the answer. But, what would be the sqrt of (1/288)?

-18, -36 I got 25.46 for my answer.

• Algebra 2 -

Geometric Mean is the nth root of the
product of a set of numbers. So when
there's 2 numbers, take the square root
of the product. When there's 3 numbers,
take the cube root of the product and so on.

1. sqrt(1/12*1/18) = sqrt(1/216) = 1/14.697 = 0.06804.

2. 25.46 is correct.
