simnplfy this and you get aproximately \(68 \frac{170713638}{250000000}\)
Hope this Helps!
The easiest way is to prime factorize \(324000\). We find that it's \(2^5\cdot3^4\cdot5^3\).
We can take out some numbers. Simplifying, we get \(2\cdot3\cdot5\sqrt[3]{2^2\cdot3}=\boxed{30\sqrt[3]{12}}\)
This is as far as it simplifies. I don't know what you mean by a fraction.
