已知a^2/3+b^2/3=4,x=a+a^1/3*b^2/3,y=b+a^2/3*b^1/3,求(x+y)^2/3+(x-y)^2/3的值

已知a^2/3+b^2/3=4,x=a+a^1/3*b^2/3,y=b+a^2/3*b^1/3,求(x+y)^2/3+(x-y)^2/3的值已知a^2/3+b^2/3=4,x=a+a^1/3*b^2/3,y=b+a^2/3*b^1/3,求(x+y)^2/3+(x-y)^2/3的值
利用已知的a^2/3+b^2/3=4变形即可:
x=a+a^1/3*b^2/3=a^1/3(a^2/3+b^2/3)=4a^1/3
同理y=4b^1/3
所以带入(x+y)^2/3+(x-y)^2/3即可算出 给分哦
