ab分之a²b化简AB分之A平方B 可以化简成为 A
a²-ab÷b²-ab化简
a²+b²+c²-ab-bc-ca 就是a的平方+b的平方+c的平方-ab-bc-ca
化简求值:(a²+ab+b²)(a²-ab+b²)(a-b)(a+b),其中a=2,b=-1
先化简((a²-b²)÷a²-ab)÷(a+(2ab+b²)÷a).当b=-1时,再从-2<a<2的范围内选合适的整数a代入求值.
化简并求值2(a²b+ab²)-2(a²b-1)-2ab²-2,其中a=-2,b=2
将 3×(a²b-ab²)-2(a²b-1)-2ab²-2 化简,其中a=﹣2,b=2先写出化简的过程 在求值.
一辆列车总重为5×10^7N,在平直水平路面上以20m/s的速度匀速行驶,列车所受的阻力为列车重的0.03倍,在10s内,列车通过的距离为200m,机车所做的功和功率分别为多少?
先化简,再求值3a²b-[2ab²-2(ab-3/2 a²b)]+2ab3a²b-[2ab²-2(ab-3/2 a²b)]+2ab.其中a,b满足│b+1│+(2a-4)²=0(要详细过程)
先化简,再求值:[ab(a²-3b)+3ab²]*(-2ab²),其中a=-1/2,b=-2jijiji
