(adsbygoogle = window.adsbygoogle || []).push({}); 1. The problem statement, all variables and given/known data

Differentiate the function:

y = x ^(-2/5)

2. Relevant equations

f'(x)lim(x->0) = (f(x+h)-f(x))/h

3. The attempt at a solution

the -2/5 exponent is giving me a hard time so all i have so far is ((x+h)^(-2/5)-x^(-2/5))/h
