Giúp tớ với!
Tính nhanh:3+3/5+3/25+3/125+3/625
Tính giá trị biểu thức :
A = 3+ 3/5+ 3/25+ 3/125+ 3/625
\(3+\frac{3}{5}+\frac{3}{25}+\frac{3}{125}+\frac{3}{625}\)
\(3+\frac{3}{5}+\frac{3}{25}+\frac{3}{125}+\frac{3}{625}\)
T-nh nhanh : (Dấu - là chữ y ngắn)
\(3+\frac{3}{5}+\frac{3}{25}+\frac{3}{125}+\frac{3}{625}\)
a,1+5/4+5/8+5/16+5/32+5/64
b,3/2+3/8+3/32+3/128+3/512
