(0.5-x)(x+0.5)(x^2+0.还有100.5*99.5、99*101*10001一共三道题,

(0.5-x)(x+0.5)(x^2+0.还有100.5*99.5、99*101*10001一共三道题,
(0.5-x)(x+0.5)(x^2+0.
还有100.5*99.5、99*101*10001一共三道题,

(0.5-x)(x+0.5)(x^2+0.还有100.5*99.5、99*101*10001一共三道题,
(0.5-x)(x+0.5)(x^2+0.25)
=（0.5-x）(0.5+x)(0.25+x²)
=(0.25-x²)(0.25+x²)
=0.0625-x^4;
100.5*99.5、
=(100+0.5)×(100-0.5)
=100²-0.5²
=10000-0.25
=9999.75;
99*101*10001
=(100-1)×(100+1)×(10000+1)
=(10000-1)(10000+1)
=100000000-1
=99999999;
