4log4 8= 2log4 16=2*2=4

We just started this today but how did you get 2log4 16 = 2 *2 = 4
Thank you
Thank you

16= 4^2 so logbase4 of 16=2

Thank you

I read that as
4 log<sub>4</sub>8
= log<sub>4</sub>8^4
= log<sub>4</sub>4096
= 6
since 4^6 = 4096
or
8 can be written as 4^(3/2)
then 4log<sub>4</sub>8
= 4log<sub>4</sub>4^(3/2)
= 4(3/2)
= 6
4 log<sub>4</sub>8
= log<sub>4</sub>8^4
= log<sub>4</sub>4096
= 6
since 4^6 = 4096
or
8 can be written as 4^(3/2)
then 4log<sub>4</sub>8
= 4log<sub>4</sub>4^(3/2)
= 4(3/2)
= 6

It was written as 4 and then the log(4)8 was raised so how do I do it-I'm really confused now
