Answer:
[tex]log_{2}[/tex] 20
Step-by-step explanation:
using the rule of logarithms
loga + logb = logab
then
[tex]log_{2}[/tex]4 + [tex]log_{2}[/tex]5
= [tex]log_{2}[/tex] (4 × 5)
= [tex]log_{2}[/tex]20
Log 2 4 + log 2 5= log 2 4x5= log 2 20
This exercises the log rule log a + log b= log ab
This exercises the log rule log a + log b= log ab
