(3+2根号2)^2010*(3-2根号2)^2011(3+2根号2)^2010*(3-2根号2)^2011(3+2根号2)^2010*(3-2根号2)^2011﹙3+2√2﹚^2010×﹙3-2√2

(3+2根号2)^2010*(3-2根号2)^2011
(3+2根号2)^2010*(3-2根号2)^2011

(3+2根号2)^2010*(3-2根号2)^2011
﹙3+2√2﹚^2010×﹙3-2√2﹚^2011
=﹙3+2√2﹚^2010×﹙3-2√2﹚^2010×﹙3-2√2﹚
=[﹙3+2√2﹚×﹙3-2√2﹚]^2010×﹙3-2√2﹚
=﹙9-8﹚^2010×﹙3-2√2﹚
=3-2√2.

(3+2根号2)*(3-2根号2)=1,所以原式=[3+2根号2)*(3-2根号2)]^2010*(3-2根号2)=3-2根号2
