• 14. 11 (2) if real numbers x and y satisfy: X / (2 ^ 10 + 5 ^ 3) + Y / (2 ^ 10 + 6 ^ 3) = 1, X / (3 ^ 10 + 5 ^ 3) + Y / (3 ^ 10 + 6 ^ 3) = 1, then x + y= Let 2 ^ 10 and 3 ^ 10 be two real roots of the equation x / (T + 5 ^ 3) + Y / (T + 6 ^ 3) = 1 about t The equation x / (T + 5 ^ 3) + Y / (T + 6 ^ 3) = 1 can be obtained It is reduced to the general form of quadratic equation t^2+(5^3+6^3-x-y)t+…… =0 (the part of the ellipsis doesn't matter) According to the relationship between root and coefficient 2^10+3^10=x+y-5^3-6^3 So x + y = 2 ^ 10 + 3 ^ 10 + 5 ^ 3 + 6 ^ 3 my question is: "x + y = 2 ^ 10 + 3 ^ 10 + 5 ^ 3 + 6 ^ 3" this is the result? How many numbers does it equal? Do you want to calculate it hard?
