Question

How to solve??? Please help!

Answer 1

We have
\(\Large 5L=2,560\times \frac{L^4}{512^2}\)\(\Large \Rightarrow 5L\times 512^2=L^4\times2,560\\\Large \Rightarrow \frac{L^4}{L}=\frac{5\times512^2}{5\times 512}=512\\\Large \Rightarrow L^3=512\)

Thus, \(\Large \color{blue}{L=\sqrt[3]{512}=8}\)
