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

Thank you

16= 4^2 so logbase4 of 16=2

I read that as
4 log₄8
= log₄8^4
= log₄4096
= 6

since 4^6 = 4096

or

8 can be written as 4^(3/2)

then 4log₄8
= 4log₄4^(3/2)
= 4(3/2)
= 6
Algebra-Reiny please look at this-Another question - Jesse, Monday, November 15, 2010 at 7:26pm
It was written as 4 and then the log(4)8 was raised so how do I do it-I'm really confused now

The choices were
4

8
