-0.25^5*0.25^5=-(0.25)^10=-1/2^20=-1/1048576 =0.00000095367431640625
利用指数的基本性质
a^m*a^n=a^(m+n)
(a^m)^n=a^mn

回答2：

负零点二五的五次方乘以正零点二五的五次方
=(-0.25)^5×(0.25)^5
=-(0.25)^10
=-0.00000095674

回答3：

(-0.25)^5×(0.25)^5
=-(0.25)^10
=-(1/4)^10
=-1/2^20
=-1/1048576

回答4：

（-0.25）^5*(0.25)^5
=((-1/4)*(1/4))^5
=(-1/16)^5
=-1/1048576

回答5：

0.25=1/4
即(-1/4)^5*(1/4)^5
=-(1/4)^10
=-1/2^20
=-1/1048576
=-0.00000095367431640625
