Cho x, y là các số thực lớn hơn 1 thỏa mãn x^2 + 9y^2 = 6xy. Tính M = (1 + log12 x + log12 y)

(National High School Graduation Exam) Given x and y are real numbers greater than 1 satisfying x² + 9y² = 6xy. Calculate M = (1 + log₁² x + log₁² y)/(2log₁² (x + 3y)). A. M = 1/2 B. M = 1/3 C. M = 1/4 D. M = 1 The question "Given x and y are real numbers greater than 1 satisfying x² + 9y² = 6xy.
