Use the properties of logarithms to condense 6log10x−4log1026 \log _ { 10 } x - 4 \log _ { 10 } 26log10x−4log102 .
A) log10(x−z) 2\log _ { 10 } ( x - z ) ^ { 2 }log10(x−z) 2
B) log10x4−log10z4\log _ { 10 } x ^ { 4 } - \log _ { 10 } z ^ { 4 }log10x4−log10z4
C) log106x4z\log _ { 10 } \frac { 6 x } { 4 z }log104z6x
D) log10x6z4\log _ { 10 } \frac { x ^ { 6 } } { z ^ { 4 } }log10z4x6
E) log10(6x−4z) \log _ { 10 } ( 6 x - 4 z ) log10(6x−4z)
Properties
Characteristics or attributes that help in identifying or describing mathematical figures, expressions or equations.
Logarithms
In mathematics, the exponent or power to which a base must be raised to yield a specific number.
Condense
In mathematics, to condense an expression means to simplify it into a more compact form, often by using properties of logarithms or exponents.
- Exploit logarithmic properties to conduct expansion and condensation of logarithmic terms.

6log10x−4log102=log10(x6)−log10(24)=log10(x624)=log10(x616)=log10(x6)−log10(16)=log10(x616)=(D) log10x6z4\begin{align*}6\log_{10}x - 4\log_{10}2 &= \log_{10}(x^6) - \log_{10}(2^4) \\&= \log_{10}\left(\frac{x^6}{2^4}\right) \\&= \log_{10}\left(\frac{x^6}{16}\right) \\&= \log_{10}(x^6) - \log_{10}(16) \\&= \log_{10}\left(\frac{x^6}{16}\right) \\&= \boxed{\textbf{(D) } \log _ { 10 } \frac { x ^ { 6 } } { z ^ { 4 } }} \end{align*}6log10x−4log102=log10(x6)−log10(24)=log10(24x6)=log10(16x6)=log10(x6)−log10(16)=log10(16x6)=(D) log10z4x6
