Question

chứng minh rằng

51\2*52\1*...*100\2=1*3*5..*99

Answer 1

51/2* 52/2* ....*100/2 = [ 51*53*55*..*99 ]*[52*54*56*...*100]/2^50 
= [ 51*53*55*..*99 ]*[26*27*28*...*50]*2^25/2^50 
= [ 51*53*55*..*99 ]*[27**29*...*49]*[26*28*30*..50)/2^25 
tiếp tục phân tích 26*28*30*..50 / 2^25 sẽ suy ra kết quả
