(-2)^2003 *(-0.5)^2004= ?
(-2)^100+(-2)^101=?

① (-2)^2003 *(-0.5)^2004
= (-2)^2003 *(-0.5)^2003 * (-0.5)
= [(-2) * (-0.5)]^2003 * (-0.5)
= 1^2003 * (-0.5)
= -0.5

② (-2)^100+(-2)^101
= (-2)^100+(-2)^100 * (-2)
= (-2)^100 * [1+(-2)]
= - 2^100

1.(-2)^2003 *(-0.5)^2004= 1^2003*(-0.5)=-0.5
2.(-2)^100+(-2)^101=2^100-2^101=-2^100

(-2)^2003 *(-0.5)^2004= 【(-2)^2003 *(-0.5)^2003】*(-0.5)
= [(-2) *(-0.5)]^2003*(-0.5)= -0.5
(-2)^100+(-2)^101=(-2)^100*1+(-2)^100*(-2)=
[(-2)^100+(-2)^100](-2+1)=-(2^100)

(-2)^2003 *(-0.5)^2004
=-2^2003×(1/2)2004
=-2^2003×1/(2^2004)
=-1/2.
(-2)^100+(-2)^101
=2^100-2^101
=2^100-2×2^100
=(1-2)×2^100
=-2^100.
