hey so i have a problem with my math homework in adv algebra 2. i need to answer this, if anyone could show me how to it wold be greatly apreciated, the problem is:

**log***x*^3=(log*x)^3*

so there is three answers, one answer is 1.

another one would be -1, not so sure about the 3rd answer though, sry

I'm assuming the question is:

log(x^3)=(logx)^3

It's all basic log rules

log(x^3) = logxlogxlogx

log(x^3) = log(3x)

x^3 = 3x

x(x^2 - 3) = 0

x = 0, sqrt(3)

log(x^3)=(logx)^3

It's all basic log rules

log(x^3) = logxlogxlogx

log(x^3) = log(3x)

x^3 = 3x

x(x^2 - 3) = 0

x = 0, sqrt(3)

wait so what are the three answers? thank your my hero

Im not sure if Im getting the notation right but my answers were x=1,exp(sqrt(3)),exp(-sqrt(3))

log(x^3)=(logx)^3

3log(x)=log(x)^3

3log(x)-log(x)^3=0

let y=log(x)

3y-y^3=0

-y(y^2-3)=0

y=0,sqrt(3),-sqrt(3)

but then you have to sub back the y=log(x)

0=log(x) --> x=1

sqrt(3)=log(x) --> x=exp(sqrt(3))

-sqrt(3)=log(x) --> x=exp(-sqrt(3))

log(x^3)=(logx)^3

3log(x)=log(x)^3

3log(x)-log(x)^3=0

let y=log(x)

3y-y^3=0

-y(y^2-3)=0

y=0,sqrt(3),-sqrt(3)

but then you have to sub back the y=log(x)

0=log(x) --> x=1

sqrt(3)=log(x) --> x=exp(sqrt(3))

-sqrt(3)=log(x) --> x=exp(-sqrt(3))

log(x)^3 = log(3x) by the rules of logarithms.

So, the original equation can be rewritten as

log(x^3) = log(3x)

Raise both sides to the base power, which eliminates the logs, leaving

x^3 = 3x

Subtract 3x

x^3 - 3x = 0

Factor out an x

x(x^2 - 3) = 0

The x term that was factored out gives an answer of 0, so you solve the remaining term

x^2 - 3 = 0 ----> x^2 = 3 ----> x = sqrt3

Keeping in mind that square roots give a positive and negative answer, your 3 solutions would be

x = 0

x = sqrt3

x = -sqrt3

So, the original equation can be rewritten as

log(x^3) = log(3x)

Raise both sides to the base power, which eliminates the logs, leaving

x^3 = 3x

Subtract 3x

x^3 - 3x = 0

Factor out an x

x(x^2 - 3) = 0

The x term that was factored out gives an answer of 0, so you solve the remaining term

x^2 - 3 = 0 ----> x^2 = 3 ----> x = sqrt3

Keeping in mind that square roots give a positive and negative answer, your 3 solutions would be

x = 0

x = sqrt3

x = -sqrt3

now you got me sittin here playin with my balls tryin to figure out what youre talking about. -swick825

This is wrong, as you already eliminated the log function, you don't need to add it back into the problem at the end. Additionally, the are logs with an unspecified base (assumed to be 10, I guess), but certainly not natural logs, so there wouldn't be an exponential function. e only arises from the ln function.

youre an idiot. what he is doing is subbing logx with Y. if y=something, then logx=something. you cant just get rid of a log completely. what he did is perfect

Yea your right.. I just got done with logs

as he said you bring the Coefficient out to the front of the log, NOT in to the 3...

NO YOURE WRONG. LOG x^3 DOES NOT EQUAL LOG 3X. STOP FILLING HIS BRAIN WITH INCORRECT STUFF
