Uniqueness Property
Where are you stuck?
I only know how to use this with logs
i personally am dying to know what "uniqueness property" is
@Cola_161 do you know \(\dfrac{1}{5}=5^{-1}\) ?
yes
For 23) \((\dfrac{1}{5})^{3k} = 5^{-3k}\) does it make sense to you?
It's 5^4 not -3k
I didn't touch the right hand side yet!! , just the left hand side. Be patient, please. You need understand what is going on. OK?
no I'm talking about the actually equation
i didn't solve anything, you just didn't put the exponent right for the 5
I understand. I think the person need patience is me. hahahaha... Again, \(\dfrac{1}{5})^{3k} = 5^{-3k}\) OK with this step??
yeah but how come the -3k is there for both exponents
not both exponents!!! just the left hand side
Now, I combine with the right hand side. Give me time OK? let me type the whole thing out.
\[\Huge (\dfrac{1}{5})^{3k}= 5^4\\\huge {5}^{-3k}=5^4 \] Now make comparison, you have -3k =4 solve for k , you have k = -4/3
alrighty
