若n为正整数,则(-5)的n+1的次方÷【5×(-5)的n次方】的值为?
若n为正整数,则(-5)的n+1的次方÷【5×(-5)的n次方】的值为?

若n为正整数,则(-5)的n+1的次方÷【5×(-5)的n次方】的值为?
(-5)的n+1的次方÷【5×(-5)的n次方】
=(-5)的n+1的次方÷【-(-5)×(-5)的n次方】
=-(-5)的n+1的次方÷【(-5)的n+1的次方】
=-1

(-5)^(n+1)÷[5×(-5)^n]
=(-5)^(n+1)÷[-(-5)×(-5)^n]
=(-5)^(n+1)÷[-(-5)^(n+1)]
=-(-5)^[(n+1)-(n+1)]
=-(-5)^0
=-1
