Question

math hep plz

Answer 1

solve the given equation for *X* if possible.

Answer 2

i need someone to hold my hand and guide me through this problem

Answer 3

e^2x ??? Or what? I need some context if this isn't the entire quation

Answer 4

that *2x* is pretty up there bro... it can only be power to be that high.

Answer 5

XD Alrightttt sheeesh

Answer 6

@dude
I haven't learned this yet

Answer 7

Don't complain XD

Answer 8

k thanks for trying mate. appreciated.

Answer 9

Okay you first want to get rid of e (since there are no common bases here)

So do ln() on both sides

Btw do you know what `ln()` is?

Answer 10

the natural base to natural log is *E* sooo

Answer 11

i can plug that in ??

Answer 12

ln is just the opposite of e, so you're basically cancelling it out



Also remember to use the law of logs (Moving the power to the front)

Answer 14

omg i just realized something...i've actually already done that question and i corrected my mistake on the paper... hold up, let me post the actual question that i need your help with...sorry

Answer 15

Its okay dont worry

\(\large \frac{ln(4)}{2}\) is also \(ln(2)\)

Answer 16

but my book says it's this...

Answer 17

next question :)

Answer 18

Be careful

You cannot divide \(\large\frac{ln(6)}{ln(3)}\)

Answer 19

Use this formula:
\[\frac{\log_{a}(b)}{\log_{a}(c)} = \log_{c}(b)\]

Answer 20

so what do i do ?

Answer 21

I am not sure whether you need to do that but just look at the variables chen used

Answer 22

ok? im solving for x so i need to isolate all the variables on one side

Answer 23

Yeah
\(\large \frac{ln(6)}{ln(3)}+1\) is right unless they specifically asked you to simplify completely

Answer 24

do you know the answer is

Answer 25

i've check the answer to that question.. twice.

Answer 26

Apply the base changing formula to log3(2)

Answer 27

gimme a little more info.. plz

Answer 28

As an example ^

Answer 29

omg...

Answer 30

Wasn't 2 being added to the logarithmic relation?

Answer 31

Leave the 2 alone you can evaluate log3(2) and add

Answer 32

yes... sorry.. letme correst.

Answer 33

ok what do i do now ? :/

Answer 34

Evaluate using a calculator

Answer 35

no.... i literally gave you the answer from the textbook... wait, let me rewrite the answer..

Answer 36

Is it asking you to evaluate or simplify

Answer 37

but with arithmatically i'm getting this..

Answer 38

the question says *solve for the given equation for x, if possible

Answer 39

Where's the x here?
It looks like 2 + log3(2)

Answer 40

that's logbase 3 and number 2. the whole thing is equal to x

Answer 41

they didn't write x=............the answer that i posted up there^^
just the answer

Answer 42

Keep going

Answer 43

wait, we started from ....

Answer 44

so far so good?

Answer 45

jus rework with me on this.. i forgot where we were..thanks :)

Answer 46

good so far? or am i making some sort of mistake?

Answer 47

oh ok

Answer 48

is there anything else left to do ?

Answer 49

but 3 isn't the common base tho. the common base is e

Answer 50

and how did log turn into natural log?

Answer 51

\[\frac{\ln a}{\ln b} = \log_{b}(a)\]

Answer 52

\[\frac{\log_{e}(6)}{\log_{e}(3)} = \log_{3}(6) = \log_{3}(2*3)=\log_{3}(2)+\log_{3}(3)\]

Answer 55

i think i got it... thanks mate. really appreciated your help ^~^

Answer 56
