12:(3/4-5/6)^2 7/22:3/11+7/22:4/11 làm hộ mik với 28/11/2021 Bởi Parker 12:(3/4-5/6)^2 7/22:3/11+7/22:4/11 làm hộ mik với
12:(3/4-5/6)^2 =12:(-1/12)^2 =12:1/144 =1728 7/22:3/11+7/22:4/11 =7/22.11/3+7/22.11/4 =7/22.(11/3+11/4) =7/22.77/12 =49/24 xin hay nhất ạ Bình luận
$12 : (\dfrac{3}{4} – \dfrac{5}{6})^{2}$ $= 12 : (\dfrac{-1}{12})^{2}$ $= 12 : \dfrac{1}{144}$ $= 1728$ $\dfrac{7}{22} : \dfrac{3}{11} + \dfrac{7}{22} : \dfrac{4}{11}$ $= \dfrac{7}{22} . \dfrac{11}{3} + \dfrac{7}{22} . \dfrac{11}{4}$ $= \dfrac{7}{22} . (\dfrac{11}{3} + \dfrac{11}{4})$ $= \dfrac{7}{22} . \dfrac{77}{12}$ $= \dfrac{49}{24}$ Bình luận
12:(3/4-5/6)^2
=12:(-1/12)^2
=12:1/144
=1728
7/22:3/11+7/22:4/11
=7/22.11/3+7/22.11/4
=7/22.(11/3+11/4)
=7/22.77/12
=49/24
xin hay nhất ạ
$12 : (\dfrac{3}{4} – \dfrac{5}{6})^{2}$
$= 12 : (\dfrac{-1}{12})^{2}$
$= 12 : \dfrac{1}{144}$
$= 1728$
$\dfrac{7}{22} : \dfrac{3}{11} + \dfrac{7}{22} : \dfrac{4}{11}$
$= \dfrac{7}{22} . \dfrac{11}{3} + \dfrac{7}{22} . \dfrac{11}{4}$
$= \dfrac{7}{22} . (\dfrac{11}{3} + \dfrac{11}{4})$
$= \dfrac{7}{22} . \dfrac{77}{12}$
$= \dfrac{49}{24}$
