Answer:
![\displaystyle log_\frac{1}{2}(64)=-6](https://tex.z-dn.net/?f=%5Cdisplaystyle%20log_%5Cfrac%7B1%7D%7B2%7D%2864%29%3D-6)
Step-by-step explanation:
<u>Properties of Logarithms</u>
We'll recall below the basic properties of logarithms:
![log_b(1) = 0](https://tex.z-dn.net/?f=log_b%281%29%20%3D%200)
Logarithm of the base:
![log_b(b) = 1](https://tex.z-dn.net/?f=log_b%28b%29%20%3D%201)
Product rule:
![log_b(xy) = log_b(x) + log_b(y)](https://tex.z-dn.net/?f=log_b%28xy%29%20%3D%20log_b%28x%29%20%2B%20log_b%28y%29)
Division rule:
![\displaystyle log_b(\frac{x}{y}) = log_b(x) - log_b(y)](https://tex.z-dn.net/?f=%5Cdisplaystyle%20log_b%28%5Cfrac%7Bx%7D%7By%7D%29%20%3D%20log_b%28x%29%20-%20log_b%28y%29)
Power rule:
![log_b(x^n) = n\cdot log_b(x)](https://tex.z-dn.net/?f=log_b%28x%5En%29%20%3D%20n%5Ccdot%20log_b%28x%29)
Change of base:
![\displaystyle log_b(x) = \frac{ log_a(x)}{log_a(b)}](https://tex.z-dn.net/?f=%5Cdisplaystyle%20log_b%28x%29%20%3D%20%5Cfrac%7B%20log_a%28x%29%7D%7Blog_a%28b%29%7D)
Simplifying logarithms often requires the application of one or more of the above properties.
Simplify
![\displaystyle log_\frac{1}{2}(64)](https://tex.z-dn.net/?f=%5Cdisplaystyle%20log_%5Cfrac%7B1%7D%7B2%7D%2864%29)
Factoring
.
![\displaystyle log_\frac{1}{2}(64)=\displaystyle log_\frac{1}{2}(2^6)](https://tex.z-dn.net/?f=%5Cdisplaystyle%20log_%5Cfrac%7B1%7D%7B2%7D%2864%29%3D%5Cdisplaystyle%20log_%5Cfrac%7B1%7D%7B2%7D%282%5E6%29)
Applying the power rule:
![\displaystyle log_\frac{1}{2}(64)=6\cdot log_\frac{1}{2}(2)](https://tex.z-dn.net/?f=%5Cdisplaystyle%20log_%5Cfrac%7B1%7D%7B2%7D%2864%29%3D6%5Ccdot%20log_%5Cfrac%7B1%7D%7B2%7D%282%29)
Since
![\displaystyle 2=(1/2)^{-1}](https://tex.z-dn.net/?f=%5Cdisplaystyle%202%3D%281%2F2%29%5E%7B-1%7D)
![\displaystyle log_\frac{1}{2}(64)=6\cdot log_\frac{1}{2}((1/2)^{-1})](https://tex.z-dn.net/?f=%5Cdisplaystyle%20log_%5Cfrac%7B1%7D%7B2%7D%2864%29%3D6%5Ccdot%20log_%5Cfrac%7B1%7D%7B2%7D%28%281%2F2%29%5E%7B-1%7D%29)
Applying the power rule:
![\displaystyle log_\frac{1}{2}(64)=-6\cdot log_\frac{1}{2}(\frac{1}{2})](https://tex.z-dn.net/?f=%5Cdisplaystyle%20log_%5Cfrac%7B1%7D%7B2%7D%2864%29%3D-6%5Ccdot%20log_%5Cfrac%7B1%7D%7B2%7D%28%5Cfrac%7B1%7D%7B2%7D%29)
Applying the logarithm of the base:
![\mathbf{\displaystyle log_\frac{1}{2}(64)=-6}](https://tex.z-dn.net/?f=%5Cmathbf%7B%5Cdisplaystyle%20log_%5Cfrac%7B1%7D%7B2%7D%2864%29%3D-6%7D)
