999999+999999-[6000+5000]=
So sánh B = 999999/2 - 999999/3 - 999999/6 với 0.
Giải chi tiết ra giùm mình nha
Bài này bấm máy tính 570 hoặc 500 là ra đó.
\(\frac{2999997}{6}\)-\(\frac{1999998}{6}\)-\(\frac{999999}{6}\)=0
S=9+99+999+9999+9999+.....+999999...999999(100 số)
(9+99+999+9999+...........+999.....99999)+100
=(10+100+1000+......+100000.......000)-100
=1111111......1110(99 chu so 1)- 100
9 + 99 + 999 + .....................+ 99999..999 ( 100 chữ số chữ số 9 )
= 9 + 9 * 11 + 9 * 111+........+ 9 * 111..11 ( 100 chữ số chữ số 1)
= 9 * ( 1 + 11 + 111 + ... + 1111..1)( 100 chữ số chữ số 1)
= 9 * A
= .... ( các bạn tự tính kết quả nhé )
cách tính của hoang quan chậm hơn mà khó hiểu hơn nữa
em khong biet dap an cua bai nay ?
999999+ 999999 = ?
x = 9+99+999+...+999999......9{số 999999......9 có 100 chữ số 9}. tìm x

Ta có: \(B=\frac{999999}{2}-\frac{999999}{3}-\frac{999999}{6}\)
\(B=999999\times\frac{1}{2}-999999\times\frac{1}{3}-999999\times\frac{1}{6}\)
\(B=999999\times\left(\frac{1}{2}-\frac{1}{3}-\frac{1}{6}\right)\)
\(B=999999\times\frac{3-2-1}{6}\)
\(B=999999\times\frac{0}{6}\)
\(B=999999\times0\)
\(B=0\)
Vậy \(B=0\) .
999999+1=?
999999*90000
999999-99999=??
Số cần tìm là:
999999-99999=900000
Đáp số:900000
