How to do this one?(Maths F.2)

2006-11-28 1:44 am

It is my internet maths homework. But many people in our from cannot do it.
We know the answer but we don't know how to type in!!

更新1:

以指數記數法表示 a x b x (-b) x (-b) x (-a) x a x (-a) x (-b) 。利用'^' 來輸入次方，如a的2次 x b的2次可輸入為a^2b^。

a x b x (-b) x (-b) x (-a) x a x (-a) x (-b) =a^2 x (-a)^2 x b x (-b)^3　　　　 ↑ ↑ 　↑　　　　(-b) x (-b) x (-b) ←←負負得正,再正負得返負　　　(-a) x (-a)←←←負負得正=a^2 x a^2 x b x (-b^3)=-b^4a^4
