which of he following is equal to X ? (A)x^(12/7)-x^(5/7) (B)root(12)((x^4)^(1/3)) (C) (sqrt(x^3))^(2/3) (D)x^(12/7)xxx^(7/12)

Solve for x : (3x -2)/(5x + 7) = (1)/(12)

(12times4)/(x^((4)/(7)))-(3times4)/(x^((4)/(7)))=x^((10)/(7))

lim_(xto0) ((1-3^(x)-4^(x)+12^(x)))/(sqrt((2cosx+7))-3)

Solve the following inequalities. (a) |2x-3| lt 1, (b) (x-2)^(2) ge 4 , (c) x^(2) ge 4 , (c) x^(2)+2x-8 le 0 , (d) |x^(2) -7x+12| gt x^(2)-7x+12 .

The value of x for which ((7)/(12)) ^(-4) xx ((7)/(12))^(3x) = ((7)/(12))^(5) is

(6x-7)/(2)+(9-2x)/(5)=12+(x)/(4)-(2)/(3)+(4x)/(3)

Solve: (x^(2)-4x+7)/(x^(2)-7x+12)<=(2)/(3)
