Answer 2

Answer :-

The correct answer of above question is -1260.

Solution :-

= $\frac{{36}^{ \frac{7}{2} } - {36}^{ \frac{9}{2} } } { {36}^{ \frac{5}{2} } }$

Now ,

$➛ \: 36 = {6}^{2}$

$= \frac{ {6}^{2 \times \frac{7}{2} } - {6}^{2 \times \frac{9}{2} } }{ {6}^{2 \times \frac{5}{2} } }$

$= \frac{ {6}^{7} - {6}^{9} }{ {6}^{5} }$

$= \frac{ {6}^{5 + 2} - {6}^{5 + 4} }{ {6}^{5} }$

$= \frac{ {6}^{5}. {6}^{2} - {6}^{5} . {6}^{4} }{ {6}^{5} }$

Now take 6^5 common then ,

$= \frac{ {6}^{5} ( {6}^{2} - {6}^{4} ) }{ {6}^{5} }$

Cancel 6^5

$= ( {6}^{2} - {6}^{4} )$

$= 36 - 1296$

$= - 1260$

So , answer of above question is -1260.
