Answer:

\frac{3^{5-5n}}{5}

Step-by-step explanation:

In the question,

We have been given the term to solve,

\frac{\frac{243^{n}}{5.3^{2n+1}}}{9^{n}\times 3^{n-1}}

So, on solving the equation using the BODMAS rule, we get,

\frac{243^{n}}{5.3^{2n+1}}\times \frac{1}{9^{n}\times 3^{n-1}}=\frac{3^{5}}{15.3^{2n}\times 3^{2n}\times 3^{n-1}}=\frac{3^{5}}{5(3^{2n+1}\times 3^{2n}\times 3^{n-1})}

Now, we also know that,

xᵃ × xᵇ = xᵃ⁺ᵇ

Therefore, on using the same identity in the equation, we get,

\frac{3^{5}}{5(3^{2n+1}\times 3^{2n}\times 3^{n-1})}=\frac{3^{5}}{5(3^{5n})}\\\frac{3^{5}}{5(3^{5n})}=\frac{3^{5-5n}}{5}

Because,

\frac{a^{m}}{a^{n}}=a^{m-n}

Therefore, the final solution of the equation on simplifying is given by,

\frac{\frac{243^{n}}{5.3^{2n+1}}}{9^{n}\times 3^{n-1}}=\frac{3^{5-5n}}{5}
