Question

Cho biểu thức A=999999999/2-999999999/3-999999999/6. So sánh A với 0

Answer 1

\(A=\frac{999999999}{2}-\frac{999999999}{3}-\frac{999999999}{6}\)

   \(=\frac{999999999\cdot3-999999999\cdot2-999999999}{6}\)

   \(=\frac{999999999\cdot3-999999999\cdot\left(2+1\right)}{6}\)

   \(=\frac{999999999\cdot3-999999999\cdot3}{6}=\frac{0}{6}=0\)

vậy A=0

Answer 2

tôi thề là A = 0

tôi vừa tính xong

đúng hơn là tính máy tính

Answer 3

A=999999999.(\(\frac{1}{2}-\frac{1}{3}-\frac{1}{6}\))=999999999.0=0=A
