Theorem
Theorem - For any positive integer n,
`lim_(x -> a) (x^n - a^n)/ (x - a)` = ` na^(n - 1)`
The expression in the above theorem for the limit is true even if n is any rational number and a is positive.
Proof : Dividing `(x^n – a^n)` by (x – a), we see that
`x^n – a^n = (x–a) (x^(n–1) + x^(n–2) a + x^(n–3) a^2 + ... + x a^(n–2) + a^(n–1))`
Thus ,
`lim_(x-> a) (x^n - a^n)/(x - a) = lim_(x -> a) (x^(n-1) + x^(n-2) a + x^(n-3) a^2 + ... + x a^(n - 2) + a^(n - 1))`
`= a^(n – l) + a a^(n–2) +. . . + a^(n–2) (a) +a^(n–l)`
`= a^(n–1) + a^(n – 1) +...+a^(n–1) + a^(n–1)` (n terms)
`= na ^(n - 1)` .
