9999999999 - 4444444444
1000000000-4444444444=?
cho bieu thuc A+9999999999/2-9999999999/3-9999999999/6.so sánh A với 0
\(A=\frac{\text{9999999999}}{2}-\frac{\text{9999999999}}{3}-\frac{\text{9999999999}}{6}\)
\(A=\text{9999999999}\left(\frac{1}{2}-\frac{1}{3}-\frac{1}{6}\right)\)
\(A=\text{9999999999}.0\)
\(A=0\)
Vậy A = B
A = 0 nhé bạn tôi thề là đúng luôn
bạn ko cần cảm ơn đâu cho 1 k là ok
4444444444+5523333336+536=
4444444444 + 5523333336 + 536 = 9967778316
4+44+444+...+4444444444 = ?
bố lấy trong tương tự chứ gì con biết tỏng
4+44+444+4444+............+4444444444 = ?
= 44444444444444444444444444444444444444444444444444444444444444444444444444444444444
4444444444 có chia hết cho 41 ko
Cho biểu thức : A=999999999/2+9999999999/3+9999999999/6
\(\frac{9999999999}{2}+\frac{9999999999}{3}+\frac{9999999999}{6}\)
\(=9999999999\cdot\left(\frac{1}{2}+\frac{1}{3}+\frac{1}{6}\right)\)
\(=9999999999\cdot1\)
\(=9999999999\)
Cho biểu thức: \(A=\frac{9999999999}{2}-\frac{9999999999}{3}-\frac{9999999999}{6}\)
So sánh A với số 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
\(A=9999999999.\left(\frac{1}{2}-\frac{1}{3}-\frac{1}{6}\right)\)
\(A=9999999999.0=0\)
Vậy A=0
9999999999+9999999999=?
