Answer 1

Explicație pas cu pas:

$( { \frac{3}{5}) }^{2} \times ({ \frac{3}{5} )}^{7} =( { \frac{3}{5}) }^{2 + 7} = { (\frac{3}{5}) }^{9} \\ ( {2 \frac{5}{12} )}^{5} \times ( {2 \frac{5}{12} )}^{9} = \\ {( \frac{2 \times 12 + 5}{12} )}^{5} \times ( { \frac{2 \times 12 + 5}{12}) }^{9} = ( { \frac{29}{12} )}^{5} \times ( { \frac{29}{12} )}^{9} = ( { \frac{29}{12}) }^{5 + 9} = ( { \frac{29}{12}) }^{14}$

$( { \frac{5}{9}) }^{17} \times {( \frac{5}{9} )}^{9} = ( { \frac{5}{9} )}^{17 + 9} = ( { \frac{5}{9}) }^{26}$
