so do you know that it is a hidden equation
normally i’d make the numbers the same and use the powers as the equation
but idk what to do here
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
there’s no y?
its just a substitution
im confused 😭
ohhhh
so then u get 3 values for y but how do u find out what x is?
well we know that y = 3^x
so just do each of your answers = 3^x
then solve those for x
and x has to be the same each time right?
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
ohh 😭
i got x = -1 for one of them but i can’t do the others
yep
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
i did it with logs
