What is the complexity of $\Theta((n^3)/(\log(n))^4)$ ? Or $\Theta(n \cdot (\log(n))^3)$?

Question

What is the complexity of $\Theta\big(\frac{n^3}{\\(log(n))^4}\big)$ ? Or $\Theta\big(n \cdot (\log(n))^3\big)$?

Is the first one equal to $\Theta(n^3)$?

Answer 1

Neither of these expressions can be simplified further.
