Question

Find the value of Y

A. 4 √3

B. 16

C. 8 √3

D. 8

Answer 1

Explanation:

By Geometric mean property:

`{y}^(2) = 4 * 12 \\ \therefore \: {y}^(2) = 48 \\ \therefore \: {y} = √(48) \\ \therefore \: {y} = √(16 * 3) \\ \huge \red{ \boxed {\therefore \: {y} = 4√(3) }}`

Thus, option A) 4√3 is the correct answer.
