\(64x6+81x4+17x6\)
\(=384+324+102\)
\(=708+102\)
\(=810\)
\(K\)\(minh\)\(nha!!\)
64 . 6 + 81 . 4 + 17 . 6
= 6 . (64 + 17) + 81 . 4
= 6 . 81 + 81 . 4
= 81 . (6 + 4)
= 81 . 10
= 810.
64 x 6 + 81 x 4 +17 x 6
=6 x ( 64+17) + 81 x 4
= 6 x 81 +81 x 4
= 81 x ( 6+ 4)
= 81 x 10
= 810
đúng đó k mik nha
64 x 6 + 81 x 4 + 17 x 6
= 384 + 324 + 102
= 810
tch mình nha
\(64x6+81x4+17x6\)
\(=384+324+102\)
\(=810\)
