Question
Evaluate the logarithms.a. $\log _{2} 4+\log _{2} 8$b. $\log _{2}(4 \cdot 8)$
Step 1
So, $\log _{2} 4$ is asking "2 to what power equals 4?" The answer is 2. Similarly, $\log _{2} 8$ is asking "2 to what power equals 8?" The answer is 3. So, $\log _{2} 4+\log _{2} 8 = 2 + 3 = 5$. Show more…
