Assuming All Variables Are Positive, Use Properties of Logarithms to Write

Question 17

Multiple Choice

Assuming all variables are positive, use properties of logarithms to write the expression as a sum or difference of
logarithms or multiples of logarithms.
- log⁡15(14rs) \log _ { 15 } \left( \frac { 14 \sqrt { \mathrm { r } } } { \mathrm { s } } \right)


A) log⁡15(14r) −log⁡15 s\log _ { 15 } ( 14 \sqrt { \mathrm { r } } ) - \log _ { 15 } \mathrm {~s}
B) log⁡1514+12log⁡15r−log⁡15 s\log _ { 15 } 14 + \frac { 1 } { 2 } \log _ { 15 } \mathrm { r } - \log _ { 15 } \mathrm {~s}
C) log⁡1514⋅12log⁡15r÷log⁡15 s\log _ { 15 } 14 \cdot \frac { 1 } { 2 } \log _ { 15 } \mathrm { r } \div \log _ { 15 } \mathrm {~s}
D) log⁡15s−log⁡1514−12log⁡15r\log _ { 15 } s - \log _ { 15 } 14 - \frac { 1 } { 2 } \log _ { 15 } r
