问题描述:
若A=12344×98766,B=12345×98765,比较A和B的大小.
答
A=12344×98766
=12345×98766-1×98766
=12345×98765+12345×1-1×98766
=12345×98765-86421
因为A=12345×98765-86421,B=12345×98765
所以A<B
如果不懂,欢迎追问.不好意思,我看不懂意思请你把意思告诉我好行吗?A=12344×98766=(12345-1)×98766=12345×98766-98766=12345×(98765+1)-98766=12345×98765+12345-98766=12345×98765-86421因为A=12345×98765-86421,B=12345×98765所以A<B
