use Log Rules: 1) logb(mn) = logb(m) + logb(n) 2) logb(m/n) = logb(m) – logb(n) 3) logb(mn) = n · logb(m)

Log base 2 (15) is what I'm getting :)

OpenStudy (anonymous):

thats not one of the choices

OpenStudy (anonymous):

i got 2log2 30

OpenStudy (anonymous):

Log base 2 (15)= 3.90 Log base 2 (18) = 4.16 almost near answers

OpenStudy (anonymous):

how did you get 2 log base 2 (30) show me your work ?

OpenStudy (anonymous):

one min

OpenStudy (anonymous):

sure Api :D

OpenStudy (anonymous):

so the answer is b?

OpenStudy (anonymous):

just wait a min :) let it be conformed

OpenStudy (lalaly):

2log_2 15 = log_2 (225) log_2 (225) - log_2 (5) = log_2 (225/5) = log_2 (45) log_2 (45)+log_2 (3) = log_2 (45*3) = log_2 (135)

OpenStudy (anonymous):

exactly :D I missed that point Thank you my dearest sister :)

OpenStudy (lalaly):
