3.27×4.5+4.5×5.73+4.5简便计算
解:采用分配律,
原式=3.27×4.5+4.5×5.73+4.5
=4.5x(3.27+5.73+1)
=4.5x10
=45
=4.5×(3.27+5.73+1)
=4.5×10
=45
请点采纳谢谢
3.27×4.5+4.5×5.73+4.5
=(3.27+5.73+1)×4.5
=10×4.5
=45
3.27×4.5+4.5+5.73×4.5
=(3.27+1+5.73)×4.5
=10×4.5
=45
3.27×4.5+4.5×5.73+4.5
=3.27×4.5+4.5×5.73+4.5×1
=4.5×(3.27+5.73+1)
=4.5×10
=45
