Question

Solve (lnx)^2=3

what is the formula here? D:

Answer 1

can you solve u^2=3 for u?

Answer 2

√3?

Answer 3

take the sqrt of both sides:
\[\ln(x) = \pm \sqrt3\]

Answer 4

so based on what @PaxPolaris says you have two equations to solve

Answer 5

kay wait
so ln(x)=±√3
10^(±√3)=x?

Answer 6

wait no ln is e
ln(x)=±√3
e^(±√3)=x??

Answer 7

correct

Answer 8

ah thank you

Answer 9

@PaxPolaris sorry to bother you again but say I have this
lnx = lg2
i can't seem to solve it ><

Answer 10

take e^ of both sides

Answer 11

x= e^(lg2)

Answer 12

what's e^ of both sides? /shot

Answer 13

like i mean, how do you do that? is it a square or something

Answer 14

\[\huge x=e^{\log \left( 2 \right)}\]

Answer 15

but what identity/formula are you using?

Answer 16

if ln x= c

then x=e^c ... you used this before ... i don't get what you are asking

Answer 17

oh right
haha sorry about that, i couldn't see it for a moment
