vă rog frumos!​

Answer 1

(4/3)²-(7/6)²=

=16/9-49/36=

=64/36-49/36=

=15/36=5/12

Answer 2

$\left(\dfrac{4}{3}\right)^2 - \left(\dfrac{7}{6}\right)^2 = {{\dfrac{16}{9}}^{^{\displaystyle (4}}} - \dfrac{49}{36} =$

$= \dfrac{64}{36} - \dfrac{49}{36} = \dfrac{64-49}{36} ={^{^{^{^{^{^{\displaystyle 3)}}}}}}}\!\!\!\dfrac{15}{36} = \dfrac{5}{12}$
