1、(完整版)指数运算考试练习题2。1。1指数与指数幂地运算练习题1、有理数指数幂地分类(1)正整数指数幂; (2)零指数幂;(3)负整数指数幂(4)0地正分数指数幂等于0, 0地负分数指数幂没有意义。2、有理数指数幂地性质(1) (2)(3)知能点2:无理数指数幂若0,是一个无理数,则表示一个确定地实数,上述有理指数幂地运算性质,对于无理数指数幂都适用。知能点3:根式1、根式地定义:一般地,如果,那么叫做地次方根,其中,叫做根式,叫做根指数,叫被开方数。 2、对于根式记号,要注意以下几点: (1),且; (2)当是奇数,则;当是偶数,则 ;(3)负数没有偶次方根; (4)零地任何次方根都是零。3
2、、我们规定:(1); (2)1、用根式地形式表示下列各式(1)= (2)=(3)=(4)=2、用分数指数幂地形式表示下列各式:(1)= (2) (3)=(4)= (5)=; (6) =;(7) (8)(9)(10) 3、求下列各式地值(1)= ;(2)=; (3)= ;(4)= (5)=;(6)=;(7)=;(8)=(9)=(10)= (11)4。化简(1)(2)(3)(4)=(5) =5.计算(1)(2) (3)(4)6。解下列方程(1) (2)(3)7。(1)。已知,求下列各式地值(1)=;(2)=(2)若,则地值是 (3)。若,求下列各式地值:(1)=;(2)=;版权申明本文部分内容,包
