$\log_{2} (\frac{1}{4})$

Step 1

Rewrite $\log_{2} (\frac{1}{4})$ as $\log_{2} (1) - \log_{2} (4)$ .

$\log_{2} (1) - \log_{2} (4)$

Step 2

Logarithm base $2$ of $1$ is $0$ .

$0 - \log_{2} (4)$

Step 3

Logarithm base $2$ of $4$ is $2$ .

$0 - 1 \cdot 2$

Step 4

Multiply $- 1$ by $2$ .

$0 - 2$

Step 5

Subtract $2$ from $0$ .

$- 2$
