$a) \\ \\ {2}^{9} \times {2}^{11} = {2}^{9 + 11} = {2}^{20}$

$b) \\ \\ {5}^{3} \times {5}^{12} = {5}^{3 + 12} = {5}^{15}$

$c) \\ \\ {7}^{19} : {7}^{11} = {7}^{19 - 11} = {7}^{8}$

$d) \\ \\ {3}^{23} : {3}^{12} = {3}^{23 - 12} = {3}^{11}$

$e) \\ \\ {( {2}^{9}) }^{11} = {2}^{9 \times 11} = {2}^{99}$

$f) \\ \\ {( {5}^{3}) }^{7} = {5}^{3 \times 7} = {5}^{21}$

$g) \\ \\ {2}^{9} \times {3}^{9} = (2 \times 3) ^{9} = {6}^{9}$

$h) \\ \\ {7}^{12} \times {2}^{12} = {(7 \times 2)}^{12} = {14}^{12}$

$i) \\ \\ {12}^{9} \times {4}^{9} = {(12 \times 4)}^{9} = {48}^{9}$
