Answer 1

$( \frac{5}{4}) {}^{3}$
$( \frac{21}{13} ) {}^{1}$
$( \frac{16}{4} ) {}^{12} \div ( \frac{8}{2} ) {}^{10} = ( \frac{8}{2} ) {}^{2}$

Answer 2

$a) (\frac{5}{4} )^{7} \div (\frac{ 5 }{4})^{4} = ( \frac{5}{4} )^{7 - 4} = ( \frac{5}{4} )^{3} = \frac{125}{64}$
$b)( \frac{21}{13} )^{52} \div ( \frac{21}{13} )^{51} = (\frac{21}{13} )^{52 - 51} = \frac{21}{13}$
$c)(4 \frac{1}{2})^{12} \div (4 \frac{1}{2} )^{10} = ( \frac{4 \times 2 + 1}{2} )^{12} \div ( \frac{4 \times 2 + 1}{2} )^{10}$
$c) (\frac{9}{2} )^{12} \div (\frac{9}{2} )^{10} = (\frac{9}{2} )^{2} = \frac{81}{4}$
