Trả lời :
\(132+77+198=12.11+11.7+11.18=11.\left(11+7+18\right)\)
\(=11.37\)\(=407\)
Study well!
\(132+77+198\)
\(=11\times12+11\times7+11\times18\)
\(=11\times\left(12+7+18\right)\)
\(=11\times37\)
\(=407\)
132 + 77 + 198
= 11x12+11x7+11x18
= 11x(12+7+18)
= 11x37
=407
132 + 77 + 198
= 11 x 12 + 11 x 7 + 11 x 18
= 11 x (12 + 7 + 18)
= 11 x 37
= 407
Ta có : \(132+77=199\)
\(\Rightarrow\)\(199+198\)= \(198+1+198\)= \(198.2+1\)= \(397\)
