(1+1/11+1/13+1/17)×(1/11+1/13+1/17+1/19)-(1+1/11+1/131/17+1/19)×(1/11+1/13+1/17)递等式运算
(1+1/11+1/13+1/17)×(1/11+1/13+1/17+1/19)-(1+1/11+1/131/17+1/19)×(1/11+1/13+1/17)
递等式运算
(1+1/11+1/13+1/17)×(1/11+1/13+1/17+1/19)-(1+1/11+1/131/17+1/19)×(1/11+1/13+1/17)递等式运算
令1+1/11+1/13+1/17+1/19=a;1+1/11+1/13+1/17=b;
则有:
b×(a-1)-a×(b-1)
=ab-b-ab+a
=a-b;
=1/19;
这也是递等式运算,只不过用a,b代替复杂的算式而已,你不信明天等着老师讲,你们老师肯定也是这样写的
