103.3^(x-y)=27" and "3^(x+y)=243," then "x" is equal to: "

If 3^(x-y)=27, and 3^(x+y)=243, then x is equal to a.0 b.2 c.4 d.6

If 3^(x-y) =27 and 3^(x+y) = 243 , then what is the value of x?

If log_(5)(3^(x)-4^(y))=3 and 3^((x)/(2))-2^(y)=5, then (x)/(y) is equal to

If "3x+4y:x+2y=9:4", then "3x+5y:3x-y" is equal to

if (x)/(y)=(3)/(2) then (x+y)/(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 :

If x - 27 " and " y = "log"_(3) 4, "then" x^(y) equals

If x = 27 " and " y = "log"_(3) 4, "then" x^(y) equals

If (x+y)^3=1331 and (x-y)^5=243 , then find x^2-y^2 .

If x+y+z=0 , then x^3+y^3+8 equals
