问一个题-6.28×17.6+6.28×(-23.3)-1.57×36.4等于多少?
-6.28×17.6+6.28×(-23.3)-1.57×36.4
= -6.28×(17.6+23.3+9.1)
= -6.28×50
= -314
-6.28×17.6+6.28×(-23.3)-1.57×36.4
=-6.28×17.6-6.28×23.3-6.28×9.1
=-6.28×(17.6+23.3+9.1)
=-6.28×50
=-314
-314
-6.28×17.6+6.28×(-23.3)-1.57×36.4=-314
-6.28×17.6+6.28×(-23.3)-1.57×36.4
=-6.28×17.6-6.28×23.3-6.28×9.1
=-6.28×(17.6+23.3+9.1)
=-6.28×50
