求一题同底数幂除法 (½)八次幂÷(负½)三次幂
求一题同底数幂除法 (½)八次幂÷(负½)三次幂
求一题同底数幂除法 (½)八次幂÷(负½)三次幂
(½)八次幂÷(负½)三次幂
=-(½)八次幂÷(½)三次幂
=-(½)^(8-3)
=-(½)^5
=负(½)五次幂
=-1/32
(1/2)^8 ÷ (-1/2)^3
=-(1/2)^8÷(1/2)^3
=- (2^3)/(2^8)
=- 1/(2^5)
=- 1/32
(1/2)^8/(-1/2)^3
=-(1/2)^8/(1/2)^3
=-(1/2)^5
(1/2)^8/(-1/2)^3
=-(1/2)^8/-(1/2)^3
=-(1/2)^5
=-1/32
