I don’t know how to solve this 😭 and have test next block

tropic spoke
#

6 is also 3², so x-2 2(5x+3)
3 = 3

#

And then u do x-2=2(5x+3)

cosmic elm
#

6= 3*2

tropic spoke
#

OMG💀

cosmic elm
#

It’s fine lol

tropic spoke
#

Oh ye

cosmic elm
#

I thought it was that easy too then I saw a whole page of work ;-;

tropic spoke
#

I'm not home right now I can do it in 5 mins

cosmic elm
#

tropic spoke
#

I'm home give me a min

Saint gone to meditate

#

Yo

#

Is this some sort of log problem

spare fox
#

yes

#

just write 6=3*2

uncut plaza
#

Like ln(3) times x-2= log(6) times 5x+3

spare fox
#

same thing

uncut plaza
#

🤷‍♂️

spare fox
#

i was simplifying it in terms of 2 and 3

#

in place of log 6 and 3

#

so further it can also be simplified

uncut plaza
#

So like (3 times 2)^(5x+3)

spare fox
#

ye , but like, all is same

uncut plaza
#

I think my log way is simpler but idk

spare fox
#

main in taking log

uncut plaza
#

Show me your work bro

spare fox
uncut plaza
#

Or ln 🙂

spare fox
#

i do work inside my brain 😅

uncut plaza

Why he using base 3

spare fox
#

cz base doesnt do much 🙄

uncut plaza
#

Mhm

cosmic elm

He’s a freshman taking 9th grader calc bc ;-;

uncut plaza
#

He’s around my level idk

It’s fine I have his work I can beg him to help me

uncut plaza
#

Do you understand log properties

cosmic elm
#

Yes

#

I think

uncut plaza
#

Write it in terms of log properties

cosmic elm
#

This is review ;-; I can’t remember

uncut plaza
#

Log(a^b)=b log(a)

spare fox
uncut plaza
#

Okay bro we know

spare fox
#

lol, jk

uncut plaza
#

How tf would some log equal zero though

spare fox
#

if a = 00000000000000000000000000000000000000000000000000000000000001

Ok guys wish me luck on the test 😻

uncut plaza
#

Just say lim a>0

spare fox
uncut plaza
#

Approaches

spare fox
#

see that carefully

tropic spoke
#

It's only solved with ln/log?

spare fox
#

both

#

base doesnt matter

uncut plaza
uncut plaza
#

Probably not

spare fox

#

Wait what

#

B=0 fr fr

#

Wait

spare fox
#

what?

uncut plaza
#

Nothing

spare fox
#

anything

unborn bloom
#

yo is it a must to use log

spare fox
#

btw , hows your calculus bro

spare fox
unborn bloom
#

ohhhh

#

but are u allowed

#

? 😏

spare fox
#

idk

x = negative of logarithm base 128 of 40

dapper vale
#

is it approximately

#

-1.1?

gentle elbow
#

no it's a negative for sure

#

this turns out to -0.76

gentle elbow
#

prolly due to rounding

#

using this answer we get the RHS equal to 0.02379

#

and LHS = 0.04820

#

☹️

gentle elbow
#

and RHS = 0.03856

#

yeah no the first one is correct

#

god knows what arithmetic error i did here

#

that's weird lmao, the manual calculation came out more precise than the supposedly infinitely accurate algebraic calculation

#

OH IM STUPID

#

NAH IM DELETING THAT 💀

#

okay so i entirely forgot my brain at home yesterday

#

ggs

#

the error in question was that i applied the log a + log b = log ab rule, but i accidentally did log(a) + b = log(ab)

#

whoopsies

dapper vale
#

so whats the answer

#

i got -1.1
