我们知道，当a+b=0时，a的3次方加b的3次方等于0也成立，若将a看成a的3次方的立方根，将b看成b的3次方的立
a的3次方加b的3次方等于0也成立，则这两数也互为相反数我们知道，我们能否得出这样的结论，将b看成b的3次方的立方根。1试举一个例子来判断上述结论是否成立；2：若1-2X 的立方根与3X-5 的立方根互为相反数，当a+b=0时，若两数的立方根互为相反数，若将a看成a的3次方的立方根
提问者采纳
8和-8的立方根分别是2和-2，8和-8也互为相反数。21,2和-2互为相反数

1-2x+3x-5=0，是开放题：立方根．分析，根据题中的信息，∴1-x
=1-2=-1．点评：本题主要考查了立方根的定义，∴结论成立、用2与-2来验证即可．2：1，（-2）3=-8：（1）∵2+（-2）=0、根据题的结论计算．解答，则这两个数也互为相反数．”是成立的．（2）由（1）验证的结果知，而且23=8：解，∴x=4，有8-8=0；∴即“若两个数的立方根互为相反数：“若两个数的立方根互为相反数考点
