2 log x = ? u learned that this morning

OpenStudy (anonymous):

oh ln x^2

OpenStudy (anonymous):

log X^2 - log 3 =?

OpenStudy (anonymous):

lnx^2/ln3

OpenStudy (anonymous):

ln x^2/3 = ln 243

OpenStudy (anonymous):

ln(x^2 / 3) -243

OpenStudy (anonymous):

no

OpenStudy (anonymous):

what

OpenStudy (anonymous):

e both sides

OpenStudy (anonymous):

ln (x^2/3)e=ln243e there

OpenStudy (anonymous):

no \[e^{ln}\]

OpenStudy (anonymous):

uh ok so whats next

OpenStudy (anonymous):

do it 1st :P

OpenStudy (anonymous):

e^ln (x^2 /3)=e^ln243

OpenStudy (anonymous):

what will that be? \[e^{ln x} = x\]

OpenStudy (anonymous):

my head exploding

OpenStudy (anonymous):

\[\frac{ x^2 }{ 3 }=243\] solve for x

OpenStudy (anonymous):

x^2=243-3

OpenStudy (anonymous):

x^2=240

OpenStudy (anonymous):

nope

OpenStudy (anonymous):

can i do this on a caculator

OpenStudy (anonymous):

its x^2/3 = 243 sure u can

OpenStudy (anonymous):

how

OpenStudy (anonymous):

u have to multiply both sides by something

OpenStudy (anonymous):

2

OpenStudy (anonymous):

is the answer 120
