\(\dfrac{23^2-13^2}{4\cdot3^2}=\dfrac{10\cdot36}{36}=10\).
\(\dfrac{46^2-26^2}{35^2-25^2}=\dfrac{20\cdot72}{10\cdot60}=\dfrac{12}{5}\).
\(\dfrac{96^2-54^2}{83^2-67^2}=\dfrac{42\cdot150}{16\cdot150}=\dfrac{21}{8}\).
\(72^2-2\cdot72\cdot53+53^2=(72-53)^2=361\).
\(112^2-2\cdot112\cdot56+56^2=(112-56)^2=3136\).
\(82^2+2\cdot82\cdot73+73^2=(82+73)^2=24025\).
