Câu này con thấy đc
1+1+2+2+3+3+....+100000000+100000000=2(1+2+3+...+100000000)=2x100000000x100000001:2=100000000x100000001
1+1+2+2+3+3+...........+100000000+100000000=1+1+2+2+3+3+.........100000000+10000000.có đúng ko
1+2+3+4+5+6+7+8+9+...+100000000
từ 1 đến 100000000 có 100000000 số
tổng là:
100000000+1*100000000/2=5000000005000000
đ/s:5000000005000000
số số hạng là:
(100000000-1):1+1=100000000
tổng dãy số là:
\(\frac{100000000.\left(100000000+1\right)}{2}=5,0000005._{10^{^{14}}}\)
1+2+3+4+5+6+7+8+9+...+100000000
1+2+3+4+5+6+7+8+9+....+100000000= bấm máy tính nha bạn
100000000+10000000+100000 co chia het cho 5^3 khong
Có nha bạn.
Có j thì tk và kb vs mk nha !!!
5^3=5x5x5 ma nhung thua so trong h deu chia het cho 5 nen so do cia het cho5
Bài giải
Giá trị của : 100000000 + 10000000 + 1000000 = 111000000
Giá trị của 5^3 = 5 x 5 x 5 = 125
111000000 : 125 = 888000 ( chia hết )
0x(1000000000+100000000-100000+\(\sqrt{5}\)+77653567+99999999999999999999999)= ?
