Question

计算:-8^2015×(-0.125)^2016+0.25^3？

Answer 1

-8^2015×(-0.125)^2016+0.25^3
= -2^(3×2015)×(-2)^(-2016×3)+2^(-2×3)
= -2^(2015×3+2016×3)+2^(-6)
= -2^(-3)+2^(-6)
= -1/8+1/64
= -7/64
= -0.109375

Answer 2

-8^2015×(-0.125)^2016+0.25^3
=-8²º¹⁵×(-0.125)²º¹⁶+0.25³
=-8²º¹⁵×(0.125)²º¹⁶+0.25³
=-8²º¹⁵×(0.125)²º¹⁵×0.125+0.25³
=-(8×0.125)²º¹⁵×0.125+0.25³
=-(1)²º¹⁵×0.125+0.25³
=-1×0.125+0.25³
=-0.125+0.25³
=-0.125+0.015625
=-0.109375
