+56 What is the value of $\sqrt[3]{2a^2 b^4} + \dfrac{a - c}{(b+c)^2}$ if $a = 4$,b = 2 c = -5?
+1832 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! :)
