`sqrt(9^(4x^2))=?`
(a) `9^(2x)` (b) `3^(2x^(2))` (c) `3^(2x)` (d) `9^(2x^(2))`

If sqrt(9^(x))=3sqrt(9^(2)) , then x =

(1) / (3) x ^ (2) -2x-9

(x+4)/(x^(2)-9)-(2)/(x+3)<(4x)/(3x-x^(2))

((2x-1)(x+3)(2-x)(1-x)^(2))/(x^(4)(x+6)(x-9)(2x^(2)+4x+9))<0

The value of: (9^(x)(9^(x-1)))^(x)/(9^(x+1).3^(2x-2)){(729^(x/3))/81}^(-x) + (3^(a) -2^(3) .3^(a-2))/(3^(a) -3^(a-1)) is:

If 3x+(2)/(x)=7, then (9x^(2)-(4)/(x^(2)))=25 (b) 35(c)49(d)30

Evaluate lim_(x to sqrt(3)) (3x^(8) + x^(7) - 11x^(6) - 2x^(5) 9x^(4) - x^(3) + 35x^(2) + 6x + 30)/(x^(5) - 2x^(4) + 4x^(2) - 9x + 6)
