x – 0.1  – 0.01 – 0.001 0.001 0.01 0.1
f(x) 0.2911 0.2891 0.2886 0.2886 0.2885 0.28631

उत्तर

Let f(x) = `lim_(x -> 0) (sqrt(x + 3) - sqrt(3))/x`

x – 0.1  – 0.01 – 0.001 0.001 0.01 0.1
f(x)

`(sqrt(3 - 0.1) - sqrt(3))/(- 0.1)`

= `(1.703 - 1.732)/(- 0.1)`

= 0.29

`(sqrt(3 - 00.1) - sqrt(3))/(- 0.01)`

= `(1.703 - 1.732)/(- 0.01)`

= 0.288

`(sqrt(3 - 0.001) - sqrt(3))/(- 0.001)`

= `(0.000284)/(- 0.001)`

= 0.288

`(sqrt(3 + 0.001) - sqrt(3))/(- 0.001)`

= `(0.000289)/(0.001)`

= 0.289

`(sqrt(3 + 0.01) - sqrt(3))/(0.01)`

= `(0.00288)/(0.01)`

= 0.288

`(sqrt(3 + 0.1) - sqrt(3))/(0.1)`

= `(0.0286)/(0.1)`

= 0.286

`lim_(x -> 0) (sqrt(x + 3) - sqrt(3))/x` = 0.288
