Question

Find the geometric mean between 12 and 2. Write your answer in radical form or round to the nearest tenth, if necessary.

Answer 1

Answer:

Geometric mean of two numbers is squre root of thir product.

Given numbers are 12,20

Geometric mean = √(12*20)

= √240

= 15.49

= 15.5

Answer 2

$\bf \: Geometric \: mean \: = \sqrt{12 \times 2 \: }$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \:\ \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \bf = \sqrt{24 \: }$

$\: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \: \bf = 12$

$\bf \: nearest \: tenth, \: = 10$
