(9)^1/3 x (3)^1/3

The value of {(x-y)^3+(y-z)^3+(z-x)^3}/{9(x-y)(y-z)(z-x)} (1) 0 (2) 1/9 (3) 1/3 (4) 1

Evaluate the following limit: (lim)_(x->3)(x^2-9)(1/(x+3)+1/(x-3))

Show that 1 + 1/3 + (1.3)/(3.6) + (1.3.5)/(3.6.9) + ….. = sqrt3

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

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

If x = (9b - 3ab)/(3/a - a/3) , what is x? (1) (9ab)/(3 + a) = 18/5 (2) b = 1

Evaluate the following limits : Lim_(xto3) (x^(2)-9) (1/(x+3)+1/(x-3))

(2)/(root(3)(9) - root(3)(3)+1) - (1)/(root(3)(9)+root(3)(3)+1) = 1) 1 , 2) -1 , 3) root(3)(3) , 4) - root(3)(3)

9xx(-1/3)xx(-3)xx(-1/9)= (a) 1 (b) -1 (c) -3 (d) 3

If A=[91,3,9,27),(3,9,27,1),(9,27,1,3),(27,1,3,9)] then det A= (A) 0 (B) -80^3 (C) 80^3 (D) 81^3
