Use the properties of logarithms to condense log12(x+4) −4log12x\log _ { 12 } ( x + 4 ) - 4 \log _ { 12 } xlog12(x+4) −4log12x .
A) log12(x+4−x4) \log _ { 12 } \left( x + 4 - x ^ { 4 } \right) log12(x+4−x4)
B) log12(x+4x) 4\log _ { 12 } \left( \frac { x + 4 } { x } \right) ^ { 4 }log12(xx+4) 4
C) log12(−3x+4) \log _ { 12 } ( - 3 x + 4 ) log12(−3x+4)
D) log12x+44x\log _ { 12 } \frac { x + 4 } { 4 x }log124xx+4
E) log12x+4x4\log _ { 12 } \frac { x + 4 } { x ^ { 4 } }log12x4x+4
Properties

Logarithms
Mathematical operations that are the inverse of exponentiation, indicating the power to which a base number is raised to obtain a particular number.
Condense
To make something denser or more compact, especially in the context of writing or presenting information.

Final Answer :
E
Explanation :
The properties of logarithms allow us to combine the terms into a single logarithm. The subtraction of logs corresponds to division, and the coefficient 4 in front of the second log can be rewritten as an exponent inside the log, leading to log12(x+4)−4log12x=log12x+4x4\log _ { 12 } ( x + 4 ) - 4 \log _ { 12 } x = \log _ { 12 } \frac { x + 4 } { x ^ { 4 } }log12(x+4)−4log12x=log12x4x+4 .
