Answer 1

$\frac{ {10}^{ - 3 + 5} }{ {10}^{1 + 4} } = \\ \\ \frac{ {10}^{2} }{ {10}^{5} } = \\ \\ {10}^{2 - 5} = {10}^{ - 3}$

$\frac{ {7}^{4 + ( - 3) + 2}}{ {7}^{3 - ( - 2)} } = \\ \\ \frac{ {7}^{3} }{ {7}^{5} } = \\ \\ {7}^{3 - 5} = {7}^{ - 2}$

$\frac{ {2}^{ - 3 + 5} }{ {2}^{1 + 4} } = \\ \\ \frac{ {2}^{2} }{ {2}^{5} } = \\ \\ {2}^{2 - 5} = {2}^{ - 3}$

$\frac{ {x}^{(5 \cdot2) + (2 \cdot3)} }{{x}^{4}} = \\ \\ \frac{ {x}^{16} }{ {x}^{4} } = \\ \\ {x}^{16 - 4} = {x}^{12}$
