The foci of the hyperbola 3(y-1)^2-4(x-2)^2=12 are (0,sqrt(7)) b. (-2,1-sqrt(7)) c. 2,1-sqrt(7) d. (0)-sqrt(7)

Choose the correct answer int sqrt(x^(2)-8x+7)dx(A)(1)/(2)(x-4)sqrt(x^(2)-8x+7)+9log|x-4+sqrt(x^(2)-8x+7)|+C(1)/(2)(x+4)sqrt(x^(2)-8x+7)+9log|x+4+sqrt(x^(2)-8x+7)|+C(C)(1)/(2)(x-4)sqrt(x^(2)-8x+7)-3sqrt(2)log|x-4+sqrt(x^(2)-8x+7)|+(1)/(2)(x-4)sqrt(x^(2)-8x+7)-((9)/(2))log|x-4+sqrt(x^(2)-8x+7)|

lim_(x rarr sqrt(2))(x^(2)-3sqrt(2)x+4)/(x^(3)+7x-9sqrt(2))

If x=(1)/(2)(sqrt(7)+(1)/(sqrt(7))) ,then , log_(27)((sqrt(x^(2)-1))/(x-sqrt(x^(2)-1))) is equal to
