4a^2b-[3ab^2-(3a^2b-1)],其中a=-0.1,b=1.
4a^2b-[3ab^2-(3a^2b-1)],其中a=-0.1,b=1.
4a^2b-[3ab^2-(3a^2b-1)]
=4a^2b-3ab^2+(3a^2b-1)
=4a^2b-3ab^2+3a^2b-1
=7a^2b-3ab^2-1
=7×0.01×1-3×(-0.1)×1-1
=0.07+0.3-1
=-0.63
4a²b - [3ab² - (3a²b - 1)]
= 4a²b - 3ab² + 3a²b - 1
= 7a²b - 3ab² - 1
= 7×(-0.1)²×1 - 3×(-0.1)×1² - 1
= 0.07 + 0.3 - 1
= -0.63
4a^2b-[3ab^2-(3a^2b-1)]
=4*(-0.1)^2-[3*(-0.1)*1^2-(3*(-0.1)^2*1-1)]
=0.04-[-0.3-0.03-1]
=0.04-1.33
=-1.29
4a^2b-[3ab^2-(3a^2b-1)]
=4a^2b-[3ab^2-3a^2b+1]
=4a^2b-3ab^2+3a^2b-1
=7a^2b-3ab^2-1
当a=-0.1,b=1
原式=7×(-0.1)²×1-3×(-0.1)×1²-1
