Question 156

Multiple Choice

Rewrite the expression as the sum and/or difference of logarithms, without using exponents. Simplify if possible.
- log⁡2m5n9k2\log _ { 2 } \frac { \sqrt [ 5 ] { m } \sqrt [ 9 ] { n } } { k ^ { 2 } }


A) 5log⁡2m+9log⁡2n−2log⁡2k5 \log _ { 2 } m + 9 \log _ { 2 } n - 2 \log _ { 2 } k
B) 52log⁡2 m+92log⁡2n−12log⁡2k\frac { 5 } { 2 } \log _ { 2 } \mathrm {~m} + \frac { 9 } { 2 } \log _ { 2 } \mathrm { n } - \frac { 1 } { 2 } \log _ { 2 } \mathrm { k }
C) 15log⁡2 m⋅19log⁡2n÷2log⁡2k\frac { 1 } { 5 } \log _ { 2 } \mathrm {~m} \cdot \frac { 1 } { 9 } \log _ { 2 } \mathrm { n } \div 2 \log _ { 2 } \mathrm { k }
D) 15log⁡2 m+19log⁡2n−2log⁡2k\frac { 1 } { 5 } \log _ { 2 } \mathrm {~m} + \frac { 1 } { 9 } \log _ { 2 } \mathrm { n } - 2 \log _ { 2 } \mathrm { k }
