Question

|-|的倒數(shù)是（ ）
A．
B．3
C．-
D．-3

Answer 1

【答案】分析：根據(jù)絕對(duì)值，倒數(shù)的概念求解．
解答：解：∵|-|=，的倒數(shù)是3，
∴|-|的倒數(shù)是3．
故選B．
點(diǎn)評(píng)：主要考查絕對(duì)值，倒數(shù)的概念．
倒數(shù)的定義：若兩個(gè)數(shù)的乘積是1，我們就稱這兩個(gè)數(shù)互為倒數(shù)．
絕對(duì)值規(guī)律總結(jié)：一個(gè)正數(shù)的絕對(duì)值是它本身；一個(gè)負(fù)數(shù)的絕對(duì)值是它的相反數(shù)；0的絕對(duì)值是0．
