## Homework Statement

**NOTE**

We are not allowed to use the quotient rule. :"(

The function is

y = ( (1 + square-root(x)) / (cube-root(x^2)) )^3

## The Attempt at a Solution

I came up with a "simplified" expression.

(1 + x^0.5)^3 * (x^-2)

***This is what I did, but it seems very wrong.***

3(1 + x^.5)^2 * (0.5x^-0.5) + (1 + x^0.5)^3 * (-2x^-3)

When trying to simply that I got into a mess. :(

[3(1 + x^0.5)^2] / (2 * x^0.5) + [(1 + x^0.5)^3 * (-2x^-3)] / x^3

I'm stuck now. :(

Help please, thank you.
