赶紧来人啊

答案

3.228x(-9)+(-3.272)x9-(-1.5)x9
=-3.228x9-3.272)x9+1.5x9
=(-3.228-3.272+1.5)x9
=5x9
=45
11.35x(-2/3)²+1.05x(-2²/9）-7.7x(-4/3²）
=11.35x4/9-1.05x4/9+7.7x4/9
=(11.35-1.05+7.7)x4/9
=18x4/9
=8
215+126x214÷215x126+89
=[215+126x(215-1)]÷(215x126+89)
=(215+126x215-126)÷(215x126+89)
=(126x215+89)÷(215x126+89)
=1
