原式=-(1/10)^1000 × (-10)^1000 × (-10) + (4/15)^2015 × (15/4)^2015 × (15/4)
=-[(1/10)×(-10)]^1000 × (-10) + [(4/15)×(15/4)]^2015 × (15/4)
=-(-1)^1000 × (-10) + 1^2015 × (15/4)
=-1×(-10) + 1×(15/4)
=10 + 15/4
=55/4
=-[(1/10)×(-10)]^1000 × (-10) + [(4/15)×(15/4)]^2015 × (15/4)
=-(-1)^1000 × (-10) + 1^2015 × (15/4)
=-1×(-10) + 1×(15/4)
=10 + 15/4
=55/4
