**Find the limit of (sqrt(1+x) - 1)/(cuberoot(1+x)-1) as x-->0**

## Homework Statement

Fin limit of the follwing as x tends to 0:

[sqrt(1+x)-1]/[cuberoot(1+x)-1]

## Homework Equations

## The Attempt at a Solution

using change of variables:

let y=sqrt(1+x)

so = limit (as y tends to 1): [y-1]/cuberoot(y^2)-1]

Then i got stuck.

any help woyld be v much appreciated.

Thank you.
