Question

急急急！！！！！(-2)^2011×(-1/2)^2012

RT (-2)^2011×(-1/2)^2012 请告诉我过程还有为什么 谢谢了

Answer 1

(-2)^2011×(-1/2)^2012=(-2)^2011×(-1/2)^2011*（-1/2）
=（-2*-1/2）^2011*(-1/2)=-1*（-1/2）=1/2
（-1）的奇数次方 结果为-1，偶数次方，结果为1.

Answer 2

最后得-1/2。过程是-2^2011*(-1/2)^2012=(-1/2)*[-2*(-1/2)]^2011=-1/2

Answer 3

结果是-O.5
原式等于（-2）^2O11x（-1/2）^2011x（-1/2）=（-2x-1/2）^2011x（-1/2）=-1/2

Answer 4

(-2)^2011×(-1/2)^2012
= (-2)^2011×(-1/2)^2011×(-1/2)
=[(-2)×(-1/2)]^2011 ×(-1/2)
=1^2011 ×(-1/2)
=1×(-1/2)
=-1/2

Answer 5

(-2)^2011×(-1/2)^2012 =-(2*1/2))^2011*1/2=-1/2
