2 3.5 + 3 5.8 + 11 8.19 + 13 19.32 + 25 32.57 + 30 57.87 = 1 3 − 1 5 + 1 5 − 1 8 + 1 8 − 1 19 + 1 19 − 1 32 + 1 32 − 1 57 + 1 57 − 1 87 = 1 3 − 1 87 = 29 87 − 1 87 = 28 87
2 3.5 + 3 5.8 + 11 8.19 + 13 19.32 + 25 32.57 + 30 57.87 = 1 3 − 1 5 + 1 5 − 1 8 + 1 8 − 1 19 + 1 19 − 1 32 + 1 32 − 1 57 + 1 57 − 1 87 = 1 3 − 1 87 = 29 87 − 1 87 = 28 87
Tính A=2/3.5 + 3/5.8 + 11/8.19 + 13/19.32 + 25/32.57 + 30/57.87
tính :
S = 2/3.5 + 3/5.8 + 11/8.19 + 13/19.32 + 25/32.57 + 30/57-87
làm nhanh giúp ạ
\(\frac{2}{3.5}+\frac{3}{5.8}+\frac{11}{8.19}+\frac{13}{8.19}+\frac{25}{32.57}+\frac{30}{57.87}\)
( Dấu . là dấu nhân)
2/3.5 + 3/5.8 + 11/8.9+13/19.32+30/27.87
tính
s= 2/3.5 +3/5.8+11/8.9 + 25/32.57 + 30/57.58
.=nhân nhé
giúp mik với ! mik đang cần
cho B=2/3.5 + 3/5.8+....+30/57.87
Tính nhanh
3/5.8+11/8.19+12/19.31+70/31.101+99/101.200
Tính Q=3/5.8+11/8.19+12/19.31+70/31.101+99/101.200
3/5.8 +11/8.19 + 16/19.35
Tính :
\(\frac{3}{5.8}+\frac{11}{8.19}+\frac{12}{19.31}+\frac{70}{31.101}+\frac{99}{101.200}\)
