" 22."x^(9)-y^(9)

Factorise 2x^(9)+54y^(9)

x^(2)=-9y

IF sin ^(-1)x + sin ^(-1) y+ sin ^(-1)""z=(3pi)/(2), then the value of x^(9) +y^(9) +z^(9)-""(1)/(x^(9)y^(-9)z^(9)) is equal to -

Prove that underset(xrarry)"lim"(x^(9//2)-y^(9//2))/(x^(5//2)-y^(5//2))=(9)/(5)y^(2)

The normal to the curve 2x^(2)+y^(2)=12 at the point (2,2) cuts the curve again at (A)(-(22)/(9),-(2)/(9)) (B) ((22)/(9),(2)/(9))(C)(-2,-2)(D) none of these

The line 5 x+12 y=9 touch the hyperbola x^(2)-9 y^(2)=9 at

if (23^(9)-23^(8))/(22)=23^(x) then x=?

If e_(1) is the eccentricity of the conic 9x^(2)+4y^(2)=36 and e_(2) is the eccentricity of the conic 9x^(2)-4y^(2)=36 then e12-e22=2 b.e22-e12=2c.2 3

If x=9 is the chord of contact of tangents of x^(2)-y^(2)=9 , then show that the equation of corresponding tangents is 9x^(2)-8y^(2)-18x+9=0
