Trả lời:
\(B=1234\times6789\times\left(650-325\times2\right)\)
\(B=1234\times6789\times\left(650-650\right)\)
\(B=1234\times6789\times0\)
\(B=0\)
B = 1234 x 6789 x (650 - 325 x 2)
B = 1234 × 6789 x (650 - 650)
B = 1234 x 6789 x 0
B = 0
1234 . 6789 . ( 650 - 325 . 2 )
= 1234 . 6789 . ( 650 - 650 )
= 1234 . 6789 . 0
= 0
