英语翻译
A positive integer is called a perfect power if it can be written in the form a^b (a的b次方),where a and b are positive integers with b>=(大于或等于).for example,32 and 125 are perfect powers because 32=2^5 and 125=5^3
The increasing sequence
2,3,5,6,7,10,.
consists of all positive integers which are not perfect powers.the sum of the digits of the 1000th number in this sequence is
(A)50 (B)48 (C)52 (D)54 (E)56

当一个正整数是a的b次方的时候它被叫作perfect power(明明应该是叫perfect square嘛,这道题怎么像中国人出的啊,严重鄙视),而a和b都是正整数,并且b大于或等于什么东西(你肯定打漏了).比如:32和125是PERFECT POWER因为32==2^5 ,125=5^3.
一个递增的数列是:
2,3,5,6,7,10,.
这个数列包括所有不是perfect power的数字.那么,这个数列里的第1000个数字的各个数位的和加起来是?(比如说123的的数字和就是6这个意思.)
(A)50 (B)48 (C)52 (D)54 (E)56
林初静你真的好厉害！佩服！！我觉得他的回答是没有什么问题。
纠正一下一楼的：
perfect square
A number that has integers as its square roots
Example:
16 is a perfect square.
