（3）−81无立方根；
（4）互为相反数的两个数的立方根也互为相反数．其中正确的是( ).\(\frac{(A)(1)(2)}{(B)(1)(3)} \frac{(C)(1)(4)}{(D)(2)(4)}\)
（1）立方根是它本身的数只有3个；
（2）1 1\(1 _{27}\)的立方根是 _{3}与− _{3}；
（3）−81无立方根；
（4）互为相反数的两个数的立方根也互为相反数．其中正确的是( ).\(\frac{(A)(1)(2)}{(B)(1)(3)} \frac{(C)(1)(4)}{(D)(2)(4)}\)
答案 / 解析
答案（f_answer）
C
解析（f_ways）
(1)立方根是它本身的数有0, ±1, 共3个, 故(1)为真命题； (2) 1\(1 _{27}\)的立方根是 _{3}, 故(2)是假命题; (3)−81 的立方根为3√−81,故(3)是假命题. (4)互为相反数的两个数的立方根也互为相反数，故(4)为真命题；综上，真命题是(1)(4)；故选：C．
