If `y=2^(3^(x))`, then `y'` equals

If log_(9)x +log_(4)y = (7)/(2) and log_(9) x - log_(8)y =- (3)/(2) , then x +y equals

If log_(9)x +log_(4)y = (7)/(2) and log_(9) x - log_(8)y =- (3)/(2) , then x +y equals

if x+y=(2 pi)/(3) and cos x+cos y=(sqrt(3))/(2) then x,y is equal to:

Let y = y (x) be the solution of the differential equation ( x - x ^(3)) dy = ( y + y x^(2) - 3x^(4)) dx , x gt 2 . If y (3) = 3 then y (4) is equal to :
