We already have all the information we need to find $\sqrt[3]{2a^2 b^4} + \dfrac{a - c}{(b+c)^2}$, so let's plug them in. 

We get

$\sqrt[3]{2(4)^2 (2)^4} + \dfrac{4 +5}{(2-5)^2}$

Simplifying and multiplying everything out, we get

$\sqrt[3]{512} + \dfrac{9}{(-3)^2}\\ 8+1\\ 9$

So our final answer is 9. 

I may have made a mistake with computation. If I did, let me know. 

Thanks! :)
