152 . 75 + ( 152 + 4 ) .25 = ( 152 . 3 ) . 25 + ( 152 + 4 ) .25
= 456 . 25 + 156 . 25
= 25 . ( 456 + 156 )
= 25 . 612
= 15300
\(152\cdot75+\left(152+4\right)\cdot25\)
\(=152\cdot75+152\cdot25+25\cdot4\)
\(=152\cdot\left(75+25\right)+100\)
\(=152\cdot100+100\cdot1\)
\(=100\cdot\left(152+1\right)\)
\(=100\cdot153\)
\(=15300\)
152 . 75 + ( 152 + 4 ) . 25
= 152 . ( 25 x 4 ) + 75
= 152 . 100 + 75
= 15200 + 75
= 15275
mik nghĩ vậy thui
