Question

Find the value of Y A. 4 √3 B. 16 C. 8 √3 D. 8

Answer 1

Step-by-step explanation:

By Geometric mean property:

${y}^{2} = 4 \times 12 \\ \therefore \: {y}^{2} = 48 \\ \therefore \: {y} = \sqrt{48} \\ \therefore \: {y} = \sqrt{16 \times 3} \\ \huge \red{ \boxed {\therefore \: {y} = 4\sqrt{3} }}$

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