 \Large \underline{\tt Question} :

 \\

Simplify :

  •  \sf \dfrac{3^8 \times b^9}{(9^4) \times b^5}

 \\

 \Large \underline{\tt Solution} :

 \\

 \sf \dashrightarrow \dfrac{3^8 \times b^9}{9^4 \times b^5}

 \sf \dashrightarrow \dfrac{3^8 \times b^9}{(3^2)^4 \times b^5}

 \sf \dashrightarrow \dfrac{3^8 \times b^9}{3^{2\times 4} \times b^5}

 \sf \dashrightarrow \dfrac{\cancel{3^8} \times b^9}{\cancel{3^8} \times b^5}

 \sf \dashrightarrow \dfrac{b^9}{b^5}

 \sf \dashrightarrow \dfrac{\cancel{b}\times \cancel{b} \times \cancel{b} \times \cancel{b}\times \cancel{b}\times b\times b\times b\times b}{\cancel{b}\times \cancel{b} \times \cancel{b} \times \cancel{b}\times \cancel{b}}

 \sf \dashrightarrow \dfrac{b\times b\times b\times b}{1}

 \sf \dashrightarrow b^4

 \\

Hence, answer is b⁴.
