Answer

Explanation:

Step1: Apply power - rule of logarithms

$3\log_2x=\log_2x^3$

Step2: Remove parentheses

$3\log_2x-(\log_23 - \log_2(x + 4))=\log_2x^3-\log_23+\log_2(x + 4)$

Step3: Apply quotient - rule of logarithms

$\log_2x^3-\log_23=\log_2\frac{x^3}{3}$

Step4: Apply product - rule of logarithms

$\log_2\frac{x^3}{3}+\log_2(x + 4)=\log_2\left[\frac{x^3(x + 4)}{3}\right]$

Answer:

$\log_2\left[\frac{x^3(x + 4)}{3}\right]$
