If `sqrt(1+(7)/(9))=1+(x)/(3)`, then `x`=

If sqrt(1 + (x)/(9)) = (13)/(3) , the the value of x is

If (1)/(8!)+(3)/(7!)=(x)/(9!) then x is:

If for x(0,(1)/(4)), the derivative of tan^(-1)((6x sqrt(x))/(1-9x^(3))) is sqrt(x)g(x), then g(x) equals: (1)(3x)/(1-9x^(3))(2)(3)/(1+9x^(3))(3)(9)/(1+9x^(3)) (4) (3x sqrt(x))/(1-9x^(3))

if (x-1)/(x+1)=7/9,then x=?

the derivative of (tan^(-1)(6x sqrt(x)))/(1-9x^(3)) is sqrt(x)g(x) then g(x) is:

sqrt(((3)/(7))^(x+1))=(343)/(27

If y= (1)/(sqrt( 3x+ 7) )- (1)/(sqrt(7-3x) ),then (dy)/(dx) =
