#

so do you know that it is a hidden equation

patent current
#

but idk what to do here

ebon hill
#

so 3^(3x) = (3^x)^3

#

same logic for the other

#

then you will be able to do y = 3^x and solve from there

patent current
#

there’s no y?

ebon hill
#

its just a substitution

patent current
#

im confused 😭

ebon hill
#

just makes it look nicer

#

one sec

#

then you have that cubic to solve

patent current
#

ohhhh

ebon hill
#

dunno why i did 3 x y^3 at the start

#

should just be 3y^3

patent current
#

so then u get 3 values for y but how do u find out what x is?

ebon hill
#

well we know that y = 3^x

#

so just do each of your answers = 3^x

#

then solve those for x

patent current
#

and x has to be the same each time right?

ebon hill
#

no

#

wdym

#

x can have different answers

#

once u solve i think u get y = 1/3 , -1, -9

#

so 3^x = 1/3 or
3^x = -1 or
3^x = -9

patent current
#

ohh 😭

patent current
ebon hill
#

did u do it with logs or cuz u knew it

#

the others are not possible so give no solutions

#

because we cannot log a negative number
