Question

Va rog .. 

($( \frac{7}{5} + \frac{3}{5}) ^{2} - ( \frac{7}{5} )^{2} - (\frac{3}{5}) ^{2}$
 
$(1,7) ^{0} - 5,3 =$
  
$( \frac{3}{6} ) ^{3} - ( \frac{3}{6} ) ^{2} - ( \frac{3}{6} ) ^{1}$

$( 7^{2} ) ^{3} : 7^{2 ^{3} }$

$\frac{2}{13} - \frac{2}{13} (2 ^{2} + 3 ^{3} )$

Answer 1

(=(10/5)²-49/25-9/25=100/25-49/25-/9/25=42/25
 
1-5,-4,3

=7^6:7^6=7^6-6=7^0=1

=2/13(1-13)=-2·12/13=-24/13
