答案和解析
(1/2)的负1/2次方=2^(1/2)=√2
【负4的1/2次方*(负1/2)的1/3次方】的负3/4次方
=[(-2)*(-1/2)^(1/3)]^(-3/4)
=[(-1/2)^(-1)*(-1/2)^(1/3)]^(-3/4)
={(-1/2)^[(-1)+(1/3)]}^(-3/4)
=[(-1/2)^(-2/3)]^(-3/4)
=(-1/2)^[(-2/3)*(-3/4)]
=(-1/2)^(1/2) = =这题有问题吧= =【“负4”的负号在哪儿的?】
【负4的1/2次方*(负1/2)的1/3次方】的负3/4次方
=[(-2)*(-1/2)^(1/3)]^(-3/4)
=[(-1/2)^(-1)*(-1/2)^(1/3)]^(-3/4)
={(-1/2)^[(-1)+(1/3)]}^(-3/4)
=[(-1/2)^(-2/3)]^(-3/4)
=(-1/2)^[(-2/3)*(-3/4)]
=(-1/2)^(1/2) = =这题有问题吧= =【“负4”的负号在哪儿的?】
