1E (If 537(的102次方) were calculated,it would have 279 digits.What would the digit farthest to the right be(the ones digit)?如果求到537的102次方,会有279位数,那个位数是多少) (这个的做法瞎蒙的,数学已经远去,我把102分解成3*2*17,7的三次方后个位是3这个3再平方,就成了9,最后就求9的17次方,然后我想就每次平方后面都是1,最后就剩下一个9没有平方,是不是就是9了~这个确实是蒙的~)
2C A performance was rated on a 3-point scale by an audience.A rating of 1 was given by 30% of the audience,a rating of 2 by 60%,and a rating of 3 by 10%.To the nearest tenth,what was the average of the ratings?观众用3分为满分的方式平价一个表演,有30%的人平价1分,60%的人平价2分,10%的人平价3分,求平价平均分.0.3*1+0.6*2+0.1*3
(1)C,(2)A
1.B 2.C
