OpenStudy (anonymous):
\[\frac{9^n(3^{n+2})}{27}\]
hartnn (hartnn):
9=3^2
OpenStudy (anonymous):
You can write :
\[\large 9^n = (3)^{2n}\]

\[(9\times3)^n\]
OpenStudy (anonymous):
So:
\[\frac{3^{2n} \times 3^{n+2}}{27}\]
And now use :
\[x^a + x^b = x^{a+b}\]
OpenStudy (anonymous):
Sorry:
\[x^a \times x^b = x^{a+b}\]
OpenStudy (jiteshmeghwal9):
\[\LARGE{(3^2)^n \times 3^{n+2} \over 27}\]\[\LARGE{3^{2n+n+2}\over27}\]\[\LARGE{3^{3n+2}\over3^3}\]
OpenStudy (anonymous):
And you can also write :
\[\large 27 = 3^3\]

\[\huge \frac {(9^n(3^n+2))}{27} = \frac {27^n + 18^n} {27} = \frac{ 45} {27} \]
OpenStudy (anonymous):
Be careful @Rohangrr
OpenStudy (jiteshmeghwal9):
\[\LARGE{3^{3n+2-3}} \space \space \space \space \space [{a^b \over a^c}={a^{b-c}}]\]
OpenStudy (anonymous):
Sorry !! :) @waterineyes
OpenStudy (anonymous):
You can delete that.. @Rohangrr
