Question

Solve for X I really need some help on this :(

Answer 1

Step-by-step explanation:

By Geometric mean property:

${x} = \sqrt{12 \times 27} \\ = \sqrt{4 \times 3 \times {3}^{3} } \\ = \sqrt{ {2}^{2} \times {3}^{4} } \\ = 2 \times {3}^{2} \\ = 2 \times 9 \\ = 18 \\ \\ \huge \red { \boxed{\therefore \: x = 18}}$
