(-1/10)^-2+(-3)^0+(-0.2)^2005*(-5)^2004

(-1/10)^-2+(-3)^0+(-0.2)^2005*(-5)^2004
(-1/10)^-2+(-3)^0+(-0.2)^2005*(-5)^2004

(-1/10)^-2+(-3)^0+(-0.2)^2005*(-5)^2004
(-1/10)^-2+(-3)^0+(-0.2)^2005*(-5)^2004
=100+1-0.2×(0.2×5)^2004
=101-0.2
=100.8

(-1/10)^-2+(-3)^0+(-0.2)^2005*(-5)^2004
=100+1+(-2)*(-0.2)^2004*(-5)^2004
=100+1-2
=99

(-1/10)^-2+(-3)^0+(-0.2)^2005*(-5)^2004
=1/(-1/10)^2+1+[-2/10*(-5)]^2004*(-2/10)
=1/1/100+1+1^2004*(-1/5)
=100+1-1/5
=100又4/5
