I suggests that you use (a+b)^3=a^3+b^3+3ab(a+b)Rightarrow a^3+b^3=(a+b)^3-3ab(a+b) instead, you will need khổng lồ use it twice lượt thích this: a^3+b^3+c^3-3abc =(a+b)^3+c^3-3ab(a+b)-3abc =(a+b+c)^3-(3c(a+b)^2+3(a+b)c^2)-3ab(a+b+c) ...
How to prove a^3 + b^3 +c^3 - 3abc =1 , If a,b,c are infinite series as given in the mô tả tìm kiếm box below?
If all three expressions are considered as functions of x in Bbb R (or Bbb C, if you prefer): a(x) = 1+fracx^33!+fracx^66! + ldots ,\ b(x)=x+fracx^44!+fracx^77!+ ldots ,\ c(x)=fracx^22!+fracx^55!+fracx^88!+ ldots ...
If you require a, b, c distinct, no. The term a+b+c can't be 0 as they are all the same sign & the other term is a sum of squares which can only be 0 if a=b=c.
