If `(9^4)^2=3^x` Then value of x =

If 3^(3x)=(9)/(3^(x)) , find the value of x .

If 4:3=x^2: 12 , then the value of x\ (x >0)dot (a) 16 (b) 4 (c) 9 (d) 3

If (x-9):(3x+6) is the duplicate ratio of 4:9 , find the value of x using properties of proportion.

If f (x) =3x ^(9) -2x ^(4) +2x ^(3)-3x ^(2) +x+ cosx +5 and g (x) =f ^(-1) (x), then the value of g'(6) equals:

If 7x - 15y = 4x + y , find the value of x: y . Hence, use componendo and dividendo to find the values of : (i) (9x + 5y)/(9x - 5y) (iI) (3x^(2) + 2y^(2))/(3x^(2) - 2y^(2))

If x+1 is a factor of ax^(3)+x^(2)-2x+4a-9 , then value of a .

If (3x - 9) : (5x + 4) is the triplicate ratio of 3 : 4 , find the value of x .
