`y = (v^3 - (2v)(sqrt(v)))/v`

`y = (v(v^2 - 2(sqrt(v))))/v`

`y = v^2-2sqrt(v)`

`(dy)/(dv) = 2v-2xx1/(2sqrtv)`

`(dy)/dx = 2v-1/sqrtv`

**So the answer is;**

`(dy)/dx = 2v-1/sqrtv`

`y = (v^3 - (2v)(sqrt(v)))/v`

`y = (v(v^2 - 2(sqrt(v))))/v`

`y = v^2-2sqrt(v)`

`(dy)/(dv) = 2v-2xx1/(2sqrtv)`

`(dy)/dx = 2v-1/sqrtv`

**So the answer is;**

`(dy)/dx = 2v-1/sqrtv`
