If 3^(2x-y)=3^(x+y)=sqrt(27), the value of y is a.(1)/(2) b.(3)/(4) c.(1)/(4) d.(3)/(2)

The area (in sq.units) of the quadrilateral formed by the tangents at the end points of the latera recta to the ellipse (x^(2))/(9)+(y^(2))/(5)=1, is: (1)(27)/(4)(2)18(3)(27)/(2) (4) 27

Evaluate : (27)^(-(1)/(3)).(27)^(-(1)/(3))[(27)^((1)/(3))-(27)^((2)/(3))]
