9205 x 17 - 9205 x 3 - 9205 + 7 x 9205
= 9205 x 17 - 9205 x 3 - 9205 x1 + 7 x 9205
= 9205 x ( 17 - 3 -1 + 7)
= 9205 x 20
= 9205 x 2 x 10
= 18410 x 10
= 184100
\(\text{9205 x 17 - 9205 x 3 - 9205 + 7 x 9205}\)
\(=\text{184100}\)
Cách 2:
\(\text{9205 x 17 - 9205 x 3 - 9205 + 7 x 9205}\)
\(=\text{(17-3-1+7)x9205}\)
\(=184100\)
9205 x 17 - 9205 x 3 - 9205 + 7 x 9205
= 9205 x 17 - 9205 x 3 - 9205 x 1 + 7 x 9205
= 9205 x ( 17 - 3 - 1 +7 )
= 9205 x 20
= 185 000 .
= 9205x 17 - 9205 x3 - 9205 x 1 + 7 x 9205
= [ 17-3-1+7] x 9205
= 20x 9205
=184100
9205 x 17 - 9205 x 3 - 9205 + 7 x 9205
= 9205 x 17 - 9205 x 3 - 9205 x1 + 7 x 9205
= 9205 x ( 17 - 3 -1 + 7)
= 9205 x 20
= 9205 x 2 x 10
= 18410 x 10
= 184100
9205 x 17 - 9205 x 3 - 9205 + 7 x 9205
= 9205 x 17 - 9205 x 3 - 9205 x 1 + 7 x 9205
= 9205 x ( 17 - 3 - 1 + 7 )
= 9205 x 20
= 184100
