\(=\frac{1}{5}-\frac{1}{8}+\frac{1}{8}-\frac{1}{19}+\frac{1}{19}-\frac{1}{31}+\frac{1}{31}-\frac{1}{101}+\frac{1}{101}-\frac{1}{200}\)
\(=\frac{1}{5}-\frac{1}{200}\)
\(=\frac{39}{200}\)
Tính Q=3/5.8+11/8.19+12/19.31+70/31.101+99/101.200
Tính :
\(\frac{3}{5.8}+\frac{11}{8.19}+\frac{12}{19.31}+\frac{70}{31.101}+\frac{99}{101.200}\)
B= 3/ 5.8 + 11/ 8.19 + 12/ 19.31 + 70/ 31.101 + 99/ 101.200
x + 2/ 3 = x - 2/ 2
giúp mk vs m.n ơi!!!!
\(\frac{3}{5.8}+\frac{11}{8.19}+\frac{12}{19.31}+\frac{70}{31.101}+\frac{99}{101.200}\)=?
Cho \(A=\frac{3}{5.8}+\frac{11}{8.19}+\frac{12}{19.31}+\frac{70}{31.101}+\frac{99}{101.200}\)so sánh a và 1
tính
\(\frac{3}{5.8}+\frac{11}{8.9}+\frac{12}{19.31}+\frac{70}{31.101}+\frac{99}{101.200}\)
Tính: \(\frac{3}{5.8}+\frac{11}{8.9}+\frac{12}{19.31}+\frac{70}{31.101}+\frac{99}{101.200}\)
/Tính
3/5.8 + 11/8.19 + 12/19.31 + 70/31.10.1 + 99/101.200
Lm giúp mik đi
A=6/5.8+22/8.19+24/19.31+140/31.101+198/101.200
