1+1=5 hahaaahaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa tui là siro
7 x 7 = 49
8 x 8 = 64
9 x 9 = 81 nha bạn nhaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa
\(=\dfrac{3}{7}\cdot\dfrac{7}{3}\cdot\dfrac{7}{3}\cdot\dfrac{3}{7}\cdot\dfrac{7}{3}=1\cdot1\cdot\dfrac{7}{3}=\dfrac{7}{3}\)
3/2-1/5= 15/10 - 2/10 = 13/10
3/7x7/6= 21/42 = 1/2
1/5:3/10= 1/5 x 10/3 = 10/15 = 2/3
\(\frac{2}{7}x\frac{7}{3}=\frac{14}{21}\)
Học tốt nhé!!! Arigatou
