计算:(a-b+c)²(b-a-c)³
解:原式=(a-b+c)²[-(a-b+c)]³=-(a-b+c)⁵
=-[(a-b)+c]⁵ =-[(a-b)⁵ +5(a-b)⁴c+10(a-b)³c² +10(a-b)²c³+5(a-b)c⁴+c⁵]
(后面自己算吧!)
(a-b+c)的2次方乘以(b-a-c)的3次方
=(b-a-c)^2*(b-a-c)^3
=(b-a-c)^5
(a-b+c)的2次方乘以(b-a-c)的3次方=(b-a-c)的2次方乘以(b-a-c)的3次方
=(b-a-c)的5次方
(a-b+c)的2次方乘以(b-a-c)的3次方
解:原式=(a-b+c)的2次方乘以负(a-b+c)的3次方
=(a-b+c)的5次方
