Question

(3+2根号2)^2012*(3-根号2)^2013

错了是(3+2根号2)^2012*(3-2根号2)^2013

Answer 1

(3+2根号2)^2012*(3-2根号2)^2013
＝（3+2根号2）^2012（3－2根号2）)^2012（3－2根号2）
＝3-2根号2

Answer 2

(3+2根号2)^2012*(3-2根号2)^2013=(3+2根号2)^2012*(3-2根号2)^2012*(3-2根号2)=[(3+2根号2)( (3-2根号2))^2012] (3-2根号2)=[3^2-(2根号2)^2]^2012*(3-2根号2)= 3-2根号2

Answer 3

3减2倍跟好2

Answer 4

(3+2根号2)^2012*(3-2根号2)^2013=[(3+2根号2)( (3-2根号2))]^2012*(3-2根号2)= 3-2根号2
