Answer 1

a: 2
b: 1.248
c: 4/3
d:3/4

Answer 2

You mean
\[\log_8 16\]?

Answer 3

yes sir

Answer 4

We have
\[\log_8 16\]
it means we need to find x for which
\[8^x=16\]
Can you change the base to 2?

Answer 5

Which of the following is equivalent to log 8 16 thats all it says

Answer 6

That's fine but do you know the properties of logarithms?

Answer 7

i have no clue what a logarithm is.

Answer 8

If we have
\[\log_x y=c\]
then this implies
\[y=x^c\]
Do you get this?

Answer 9

i don't understand that.

Answer 10

i need to finish like 80 problem so i pass my math class and i don't understand them

Answer 11

problems

Answer 12

is the answer a?

Answer 13

@zackwashere I gotta go now, Sorry
I'll ask someone to help you!
@lgbasallote would you help here?

Answer 14

later

Answer 15

Howdy, Zack =)

Answer 16

yello

Answer 17

Let me show you an example.
\[\large \log_2{4}\]
Means, "What power can I raise 2 to to get 4?"
So we need to come up with a number that we can raise 2 to to get 4, and we try 2.
\[2^2 = 4\]
So that means that 2 works, and we get
\[\large \log_2{4}=2\]

Answer 18

Here's another example.
\[\large \log_2{8}\]
means that we need some power of 2 that will give us 8.
\[2^3 = 8\]
so
\[\large \log_2{8}=3\]

Answer 19

i think the answer is a am i right?

Answer 20

no

Answer 21

log_a(b) = logb/loga

Answer 22

then you can change the base

Answer 23

because you now have a ratio, so a base like 2 would be nice

Answer 24

If you choose a, then you are saying that
\[\large \log_8{16} = 2\]
Which would mean that
\[\large 8^2 = 16\]
Is that true? No, because 8^2 = 64

Answer 25

i have no clue what you guys are talking about

Answer 26

is this for a class? have you studied? because there are lots of log rules and it will take some time to get used to them, but you have to practice.

Answer 27

i fail at math and i need to finish a few math problems to pass the class

Answer 28

my friend said this site gave people answers

Answer 29

Naw. That ain't me.
