plz guys solve this question​

Answer 1

Answer:

$32n \div - 5512 { | |?| | }^{2}$

Answer 2

$\sf \implies \dfrac{ { 3}^{2n + 4} - 5 \bigg ( {3}^{2(n + 1)} \bigg )}{ {9}^{n - 1} }$

We can write 9 as 3².

$\sf \implies \dfrac{ { 3}^{2n + 4} - 5 \bigg ( {3}^{2(n + 1)} \bigg )}{ { {3}}^{2(n - 1)} }$

$\sf \implies \dfrac{ { 3}^{2n + 4} - 5 \bigg ( {3}^{2n +2} \bigg )}{ { {3}}^{2n - 2} }$

$\sf \implies \dfrac{ { 3}^{2n + 4} }{ { {3}}^{2n - 2} } - \dfrac{ 5 ( {3}^{2n +2} )}{{3}^{2n - 2}}$

$\sf \implies { { 3}^{2n + 4-( 2n - 2)} }- { 5 ( {3}^{2n +2 - ({2n - 2})} )}$

$\sf \implies { { (3)}^{2n + 4- 2n + 2} }- { 5 ( {3})^{2n +2 - 2n + 2} }$

$\sf \implies { { (3)}^{4 + 2} }- { 5 ( {3})^{ 2 + 2} }$

$\sf \implies { { (3)}^{6} }- { 5 ( {3})^{4} }$

$\sf \implies {(3})^{4} \bigg({ { 3}^{2} }- { 5 }\bigg)$

Now , 3⁴= 81 and 3²= 9

$\sf \implies 81 \bigg({ 9}- { 5 }\bigg)$

$\sf \implies 81 \times 4$

$\sf \implies 324$
