若0.00000526的立方根=0.01739,x的立方根=17.39,-5.26的立方根是y,求x和y的值

题目

若0.00000526的立方根=0.01739,x的立方根=17.39,-5.26的立方根是y,求x和y的值

答案

因为：0.00000526^(1/3)=0.01739所以：1000×[0.00000526^(1/3)]=1000×0.01739[(1000^3)×0.00000526]^(1/3)=17.39260^(1/3)=17.39又已知：x^(1/3)=17.39所以：x=260因为：0.00000526^(1/3)=0.01739所以：(-1000000...
