Find the geometric mean of 4 and 12
jonny [76]

Answer:

The Geometric Mean of 4 and 12 is 6.9

Step-by-step explanation:

Given Numbers are 4 and 12

To find : Geometric mean of the given No.

The Geometric Mean is a type of average where we multiply the nos. together and then take a square root (for two nos), cube root (for three nos) etc.

Formula for Geometric Mean is given by,

Geometric\,Mean\,of\,x_1\,,\,x_2\,,\,x_3..x_n=\sqrt[n]{x_1\times x_2\times x_3\times\,...\,\times x_n}

⇒ Geometric Mean of 4 and 12 = \sqrt{4\times12}

                                                     = \sqrt{48}

                                                     = 4\sqrt{3}

                                                     = 6.92820323028

                                                     = 6.9

Therefore, The Geometric Mean of 4 and 12 is 6.9
