" (9.) "tan y=log_(x)x

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 = log_(3)27 and y = log_(9)27 then 1/x + 1/y = ______

Draw the graph of y=log_(e)(-x),-log_(e)x,y=|log_(e)x|,y=log_(e)|x| and y=|log_(e)|x|| transforming the graph of y=log_(e)x.

if log_(9)x+log_(4)y=(7)/(2) and log_(9)x-log_(8)y=-(3)/(2) then x+y is

If x is an acute angle and y=log_(e)[tan((pi)/(4)+(x)/(2))] then cosh x*cosh y

If y=log_(10)x+log_(10)x^(1/3)+log_(10)x^(1/9)+ . . . and (2+4+6+ . . . +2y)/(3+6+9+ . . . +3y)=4/log_(10) x then find the value of x and y

If log_(3) sin x-log_(3) cos x-log_(3)(1- tan x)-log_(3)(1+tan x)= -1 , then tan2x is equal to (wherever defined)
