3^4/3^4
This should be easy, since both numerator and denominator are same.

For first one, how did you get 3?
Remember this property?
\(\Large\displaystyle \dfrac{a^m}{a^n} = a^{m-n}\)
jimthompson5910 (jim_thompson5910):
3 isn't the correct answer
OpenStudy (anonymous):
How do you do these? I am a little confused
jimthompson5910 (jim_thompson5910):

you can also think of it as
3^4/3^4 = 3^(4-4) = 3^0 = 1

That makes sense! But then what next?
jimthompson5910 (jim_thompson5910):
that's it, (3^4)/(3^4) is 1
OpenStudy (anonymous):
Oh whoops sorry I was looking at the next problem's answer choices!
OpenStudy (anonymous):
but then is it basically the same thing for the next problem?
