75x48十75x52的简便计算

我猜应该是75*48+75*5275*48+75*52=75*(48+52)=75*100=7500

=7x(48+52)=7x100=700

75*48=3*25*4*12=3*12*(25*4)=36*100=3600

您好.原式 =75x299+75x1 =75x(299+1) =75x300 =22500

75x297十75=75x(297+1)=75x298=75x(300-2)=75x300-75x2=22500-150=22350

75X48十75x5十75x47=75*(47+48+5)=75*100=7500

75*48+75*5+75*47=75*(48+5+47)=75*100=7500

简便运算:75x43+58x75一75=75x43+58x75一75x1=75x(43+58-1)=75x100=7500

75x63十37x75=75*(63+37)=75*100=7500

75x48-75+ 53x75=75x(48-1+53)=75x100=7500
