उत्तर

`lim_(x -> 0) ((1 + x)^"n" - 1)/x`

Put 1 + x = y            

∴ x = y – 1

As x → 0, y → 1

∴ `lim_(x -> 0) ((1 + x)^"n" - 1)/x`

= `lim_(y -> 1)(y^"n" - 1)/(y - 1)`

= `lim_(y -> 1)(y^"n" - 1^"n")/(y - 1)`

= n(1)n – 1         ...`[lim_(x ->"a") (x^"n" - "a"^"n")/(x - "a") = "na"^("n" -  1)]`

= n
