Question

If log(17) + log(y) = log(z), then 17 + y = z.

true or false? i thought z would be 17*y

Answer 1

since its addition it goes with multiplication

Answer 2

Yes you think right..

Answer 3

so the answer would be false

Answer 4

\[\log(a) + \log(b) = \log(ab)\]

Answer 5

what about: If ln(17x) = ln (y), then 17x = y.

Answer 6

Yes it will be false..

17y = z..

Answer 7

Yes you are right again..

Answer 8

so this is false too?

Answer 9

How??

\(log(a) = log(b) \implies a = b\)

Answer 10

\[\log(a) = \log(b) \rightarrow a = b\]

Answer 11

ah i gotcha!

Answer 12

So is it false or true ??

Answer 13

True

Answer 14

Yes you are also true..

Answer 15

Which of the following is equivalent to ln(3e^6)?

18
ln(3) + 6
36
6ln(3)
3e^6

Answer 16

Firstly use :

\[\log(ab) = \log(a) + \log(b)\]

Answer 17

a = 3 and b = \(e^6\) here..

Answer 18

dude your so helpful, i guess i just get confused when they throw an e in there but if u just look at the basic properties u can tell what to do with most of these

Answer 19

(log(x))^7 = 7log(x)

so this would be true, am i correct?

Answer 20

Yes it is correct but :

You should remember this :

\[\ln(e) = 1\]

Answer 21

\[\ln(e^6) = 6 \cdot \ln(e) \rightarrow 6 \cdot 1 \rightarrow \color{green}{6}\]

Answer 22

Which of the following is equivalent to ln(13 + e8)?

ln(13) + 8
13 + e8
104
8ln(13 + e)
None of the above

Answer 23

What do you think tell me first..

Answer 24

i thought it was ln(13) + 8, but its not

Answer 25

That is e^8 ???

Answer 26

yes

Answer 27

There is no particular formula for \(log(a + b)\)..

Answer 28

Option e> looks fine to me for this question..

Answer 29

none of the above?

Answer 30

If this is option e> then yes..

Answer 31

e> ?? im confused

Answer 32
