Answer:


\log_(2) [(x^(3)(x + 4))/(3)]

Explanation:

We have to write the following logarithmic expression as a single logarithm.

The given expression is


3\log_(2) x - [\log_(2) 3 - \log_(2)(x + 4)]

=
3\log_(2) x - \log_(2) ((3)/(x + 4))

{Since,
\log A - \log B = \log (A)/(B), from the properties of logarithmic function }

=
\log_(2) x^(3)  - \log_(2) ((3)/(x + 4))

{Since,
a\log b = \log b^(a), which also a logarithmic property}

=
\log_(2) [(x^(3))/((3)/(x + 4))]

=
\log_(2) [(x^(3)(x + 4))/(3)] (Answer)
