उत्तर

y = `sqrt(x +sqrt(x)`

y = `[x + x^(1/2)]^(1/2)`

y = f(g(x))

`("d"y)/("d"x)` = f'(g(x)) . g'(x)

`("d"y)/("d"x) = 1/2 [x + x^(1/2)]^(1/2 - 1)  [1 + 1/2 x^(1/2 - 1)]`

`("d"y)/("d"x) = 1/2[x + x^(1/2)]^(- 1/2) [1 + 1/2 x^(- 1/2)]`

= `1/[2x + x^(1/2)]^(1/2) [1 + 1/(2x^(1/2))]`

= `1/(2sqrt(x + sqrt(x))) xx [(2x^(1/2) + 1)/(2x^(1/2))]`

= `1/(2sqrt(x + sqrt(x))) xx [(2sqrt(x) + 1)/(2sqrt(x))]`

`("d"y)/("d"x) = (2sqrt(x) + 1)/(4sqrt(x) * sqrt(x  sqrt(x))`
