1/1.2 + 2/2.4 + 3/4.7 +...+ 10/46.56 = ?
1/1.2+2/2.4+3/4.7+............+10/46.56
P=1/1.2 + 2/2.4 + 3/4.7 +.........+10/46.56
giúp mình với các bạn ơi!
\(D=\frac{1}{1.2}+\frac{2}{2.4}+\frac{3}{4.7}+...+\frac{10}{46.56}\)
Tính \(\frac{1}{1.2}+\frac{2}{2.4}+\frac{3}{4.7}+...+\frac{10}{46.56}\)
1/1.2 + 1/2.4 + 1/4.7 + ... + 1/46.56
\(P=\frac{1}{1.2}+\frac{2}{2.4}+\frac{3}{4.7}+...+\frac{10}{46.56}\)
giúp mih vs nhoa
tính
\(P=\frac{1}{1.2}+\frac{2}{2.4}+\frac{3}{4.7}+...+\frac{10}{46.56}\)
giups mih vs
P = \(\frac{1}{1.2}+\frac{2}{2.4}+\frac{3}{4.7}+...+\frac{10}{46.56}\)
(nhớ có cả lời giải nhé )
