We can convert the logarithmic equation to exponential equation to find its equivalent equation.

y= log_{ \frac{1}{2} }(x) \\  \\ 


Shifting the base of log(1/2) to the other side of the equation, we can write:

(\frac{1}{2})^{y} =x \\  \\ 
x= \frac{ 1^{y} }{ 2^{y} }  \\  \\ 
x= \frac{1}{ 2^{y} } \\  \\ 
x= 2^{-y}
