Evaluate `lim_(x->3) (x^4-81)/(x^2-9)`

lim_(x-> 3) ((x^4 -81)/(x-3))

lim_(x-> 3) ((x^4 -81)/(x-3)) = ?

Evaluate, lim_(x to 1) (x^(4)-1)/(x-1)=lim_(x to k) (x^(3)-k^(3))/(x^(2)-k^(2)) , then find the value of k.

Evaluate lim_(xto3) ((x^(2)-9))/((x-3))

lim_(x rarr3)(x^(4)-81)/(2x^(2)-5x-3)

Evaluate, lim_(x to 2) (x^(3) - 8)/(x^(2) - 4)

Evaluate lim_(xtooo) ((x^(2)+x-1)/(3x^(2)+2x+4))^((3x^(2)+x)/(x-2))

lim_(x rarr3)(x^(3)-27)/(x^(2)-9)

Evaluate the following limit: (lim)_(x rarr3)(x^(4)-81)/(x^(2)-9)

Evaluate lim_(x to 3) (x^(7) - 2187)/(x - 81)
