`3^(2x-3)-9^(x-1)+2 7^(2x/3)=675`

Check whether the following are quadratic equations : (1) (x-3)^(2)=x(2x-5) (2) (2x-3)(8x+1) = (4x+5)(4x-5) (3) (5x+3)(x-2)=(4x+3)(2x-1) (4) (2x+5)^(3)=8(x-1)^(3) (5) x^(2)+7x-8=x(x+5) (6) x^(3)+9x^(2)-7x+2=(x+3)^(3)

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:

Find the sum of the following algebraic expressions : 3x^(3) - 5x^(2) + 2x + 1 , 3x - 2x^(3) - x^(3) , 2x^(2) - 7x + 9

If 2^(x).9^(2x+3) = 7^(x+5) , then x =

If 2^(x).9^(2x+3) = 7^(x+5) , then x =

If |{:(x^(2) +x , 3x - 1 , -x + 3),(2x +1 , 2 + x^(2) , x^(3) - 3),(x - 3, x^(2) + 4, 3x):}| = a_(0) + a_(1) x + a_(2) x^(2) + .... + x_(7) x^(7), then the value of a_(0) is

Simplify the following : 5x^(4) - 7x^(2) +8x - 1 +3x^(2) - 9x^(2) + 7 - 3x^(4)+11x - 2 +8x^(2)

Solve for x.(2x)/(x-3)+(1)/(2x+3)+(3x+9)/((x-3)(2x+3))=0x!=3,-(3)/(2)

Solve the following equation: (2x)/(x-3)+(1)/(2x+3)+(3x+9)/((x-3)(2x+3))=0 , x ne 3, x ne -(3)/(2)
