Mathematics

$\large\boxed{\log_2\dfrac{x^3}{\left(\dfrac{3}{x+4}\right)}}$

Step-by-step explanation:

$\text{Use}\\\\\log_ab^n=n\log_ab\\\\\log_a\left(\dfrac{c}{d}\right)=\log_ac-\log_ad\\\\==============================$

$\text{We have:}\\\\3\log_2x-(\log_23-\log_2(x+4))\\\\=\log_2x^3-\log_2\dfrac{3}{x+4}\\\\=\log_2\dfrac{x^3}{\frac{3}{x+4}}$
