Answer 1

$( \frac{ {49}^{5 \div 2} - {49}^{7 \div 2} }{ {49}^{3 \div 2} } ) \\ = \frac{ { (\sqrt{49}) }^{5} - ( { \sqrt{49} )}^{7} }{( { \sqrt{49})}^{3} } \\ = \frac{ {7}^{5} - {7}^{7} }{ {7}^{3} } \\ taking \: {7}^{3} common \: \: \\ = \frac{ {7}^{3}( {7}^{2} - {7}^{4} )}{ {7}^{3} } \\ = {7}^{2} - {7}^{4} \\ = {7}^{2} (1 - {7}^{2} ) \\ = 49(1 - 49) \\ = 49( - 48) \\ = - (2352)$

Therefore, -2352 is the answer.
