Answer 1

`\sf (3^x - 5 * 3^((x-2)))/(3^((x-3))) \\ \\ \longrightarrow \sf \frac{ {3}^(x) }{ {3}^((x - 3))} - \frac{5}{ {3}^((x - 3)) } * {3}^((x - 2)) \\ \\ \longrightarrow \sf {3}^([x - (x - 3)]) - \frac{5}{ {3}^((x - 3)) } * {3}^((x - 2)) \\ \\ \longrightarrow \sf {3}^(3) - \frac{5}{ {3}^((x - 3)) } * \frac{ {3}^(x)}{9} \\ \\ \longrightarrow \sf {3}^(3) - \frac{5}{ \bigg(\frac{ {3}^(x) }{ {3}^(3) }\bigg) } * \frac{ {3}^(x)}{9}\\ \\ \longrightarrow \sf {3}^(3) - \frac{ ({3}^(3))( 5)}{ {3}^(x) } * \frac{ {3}^(x)}{9}\\ \\ \sf \longrightarrow {3}^(3) - (5 * 3) \\ \\ \longrightarrow \sf \: 27 - 15 \\ \\ \longrightarrow \leadsto{\underline{\boxed{\sf{ \pink{ 12}}}}}`
