con người

sáng là lúc người ta sơ khai nên bò 4 chân

trưa là lúc người ta lớn biết đi bằng 2 chân

chiều là lúc người ta già đi 2 chân và 1 chân là chiếc gậy trống bằng 3 chân

tối là lúc người ta chết có 2 chân và 6 chân trống của chiếc quan tài

tik nha

Vì 1ⁿ (n > 0) luôn bằng 1 

nên 1²+1³+...+1²⁰¹²=1+1+1+...+1

Có số số 1 là : (2012 -2):1+1 =2011 (số )

=>tổng trên =1.2011=2011

tick cho mình nha
