A = 1 phần 2 + 1 phân bốn + 1 phần 8 + 1 phần 16 + 1 phần 32 +...........+1 phần 1024
tính nhanh tổng sau :
a, D=1/2+1/4+1/8+1/16+1/32+•••+1/512+1/1024
b, Đ=1/1*2+1/2*3+1/3*4+•••+1/18*19+1/19*20
c,E=1/11*16+1/16*21+1/21*26+•••1/56*26+1/61*-6
Ai nhanh thì mình tick
Tính 1/2-1/4-1/8-1/16-....-1/1024
A=1/2+1/4+1/8+1/16+.........+1/512+1/1024 = ?
A=1/2+1/4+1/8+....+1/512+1/1024
