\(A=\frac{\text{9999999999}}{2}-\frac{\text{9999999999}}{3}-\frac{\text{9999999999}}{6}\)
\(A=\text{9999999999}\left(\frac{1}{2}-\frac{1}{3}-\frac{1}{6}\right)\)
\(A=\text{9999999999}.0\)
\(A=0\)
Vậy A = B
A = 0 nhé bạn tôi thề là đúng luôn

=(.....)*0=0
Nhân xét biểu thức A, ta thấy:
\(\frac{9999999999}{2}>\frac{9999999999}{3}>\frac{9999999999}{6}>0\)
=> \(A>0\left(đpcm\right)\)
ta có 9999999999/2=9999999999*3/2*3
9999999999/3=9999999999*2/3*2
suy ra 9999999999*3/2*3 - 9999999999*2/3*2=9999999999*3-9999999999*2/6=9999999999/6
suy ra A=9999999999/6-9999999999/6=0
vậy A=0
1000000000 . 1000000000 = 10000000002 = 1000000000000000000
k cho mik nha
bằng 10999999999
= 1999999999
