lim_(x rarr a)(x^(2/7)-a^(2/7))/(x-a)

If lim_(x rarr a) (x^(7)-a^(7))/(x-a)=7 , then find the number of possible real values of a.

Evaluate the following limit: (lim)_(x rarr a)(x^(5/7)-a^(5/7))/(x^(2/7)-a^(2/7))

If lim_(x rarr-a)(x^(7)+a^(7))/(x+a)=7, where a<0 then there exists at least one a for which point (a,2) where lies on the line

lim_(x rarr a) (x^(7/6)-a^(7/6))/(x^(3/5)-a^(3/5)), (a gt 0) =

Evaluate: lim_(x rarr a) (x^(14)-a^(14))/(x^(-7)-a^(-7)) .

Evaluate: lim_(x rarr 0)(e^(13x)-e^(7x))/(x)

lim_(x rarr pi)(x-(22)/(7))
