4.1.1n次方根与分数指数幂学习目标:1.理解根式的定义和性质、分数指数幂的定义.2.把握分式与负整数指数幂、根式与正分数指数幂的内在联系.学习重点:1.根式的定义和性质.2.根式与分数指数幂的联系.3.正分数指数幂与负分数指数幂的联系.学习难点:1.指数幂的含义及其与根式的互化.2.na n与(na)n的区别与联系.知识导学知识点一根式的定义(1)a的n次方根的定义:一般地,如果x n=a,那么x叫做a的n次方根,其中n>1,且n∈N*.(2)a的n次方根的表示①当n是奇数时,a的n次方根表示为na,a∈R;②当n是偶数时,a的n次方根表示为±na,其中-na表示a的负的n次方根,a∈[0,+∞).(3)根式:式子na叫做根式,这里n叫做根指数,a叫做被开方数.知识点二根式的性质(1)(na)n=a(n为奇数时,a∈R;n为偶数时,a≥0,且n>1).(2)na n=⎩⎪⎨⎪⎧a(n为奇数,且n>1),|a|(n为偶数,且n>1).知识点三分数指数幂的意义(1)a mn=na m,a-mn=1amn=1na m(其中a>0,m,n∈N*,且n>1).(2)0的正分数指数幂等于,0的负分数指数幂.知识点四有理数指数幂的运算性质(1)a r a s=(a>0,r,s∈Q).(2)(a r)s=(a>0,r,s∈Q).(3)(ab)r=(a>0,b>0,r∈Q).新知拓展1.na n与(na)n的区别(1)na n是实数a n的n次方根,是一个恒有意义的式子,不受n的奇偶限制,但这个式子的值受n的奇偶限制.其算法是对a先乘方,再开方(都是n次),结果不一定等于a,当n为奇数时,na n=a;当n为偶数时,na n=|a|=⎩⎪⎨⎪⎧a,a≥0,-a,a<0.(2)(na)n是实数a的n次方根的n次幂,其中实数a的取值范围由n的奇偶决定.其算法是对a先开方,后乘方(都是n次),结果恒等于a.2.分数指数幂的理解(1)分数指数幂是指数概念的又一推广,分数指数幂a mn不可理解为mn个a相乘,它是根式的一种新的写法.在这样的规定下,根式与分数指数幂是表示相同意义的量,只是形式不同而已.(2)把根式na m化成分数指数幂的形式时,不要轻易对mn进行约分.3.在保证相应的根式有意义的前提下,负数也存在分数指数幂,如(-5)23=3(-5)2有意义,但(-5)34=4(-5)3就没有意义.评价自测1.判一判(正确的打“√”,错误的打“×”)(1)因为32=9,所以3是9的平方根.()(2)当n∈N*时,(n-16)n都有意义.()(3)(3-π)2=π-3.()2.做一做(请把正确的答案写在横线上) (1)用根式的形式表示下列各式(a>0):①a 15 =________;②a 34=________; ③a -35 =________;④a -23=________.(2)将下列根式写成分数指数幂的形式(其中a >b >0). ①5(a -b )7=________;②4(a 2-b 2)3=________; ③4a 2b -ab 2=________;④4(a 2-b 2)2=________. (3)若n 为偶数时, n(x -1)n =x -1,则x 的取值范围为________.核心素养题型一 根式的概念 利用根式的性质化简例1 (1)①16的平方根为________,-27的5次方根为________; ②已知x 7=6,则x =________;③若4x -2有意义,则实数x 的取值范围是________; (2)化简:①n(x -π)n (x <π,n ∈N *);②4a 2-4a +1⎝⎛⎭⎫a ≤12. 金版点睛1.判断关于n 次方根的结论应关注的两点 (1)n 的奇偶性决定了n 次方根的个数;(2)n 为奇数时,a 的正负决定着n 次方根的符号. 2.根式化简求值解题思路解决根式的化简问题,首先要分清根式为奇次根式还是偶次根式,然后运用根式的性质进行解答.跟踪训练1 (1)下列说法正确的个数是( )①16的4次方根是2;②416的运算结果是±2;③当n 为大于1的奇数时,na 对任意a ∈R 都有意义;④当n 为大于1的偶数时,na 只有当a ≥0时才有意义. A .1 B .2 C .3 D .4 (2)已知m 10=2,则m 等于( ) A.102 B .-102 C.210 D .±102(3)化简下列各式: ①3-27;②(3-9)3;③ (a -b )2.题型二 根式与分数指数幂的互化例2 下列根式与分数指数幂的互化中,正确的是( ) A.-4x =(-x )14 (x >0)B.x - 15 =-5x (x ≠0)C.⎝⎛⎭⎫x y -34 =4⎝⎛⎭⎫y x 3(xy >0) D.8y 2=y 14 金版点睛根式与分数指数幂互化依据(1)在解决根式与分数指数幂互化的问题时,关键是熟记根式与分数指数幂的转化式子:a m n=n a m和a - mn =1a m n= 1n a m ,其中字母a 要使式子有意义.(2)将含有多重根号的根式化为分数指数幂的途径有两条:一是由里向外化为分数指数幂;二是由外向里化为分数指数幂.跟踪训练2 用分数指数幂表示下列各式: (1) 3ab 2(ab )3(a >0,b >0); (2)13x (5x 2)2(x >0).题型三 多重根式的化简 例3 化简: 3+22+ 3-2 2.金版点睛 形如 m ±2n (m >0,n >0)的双重根式,一般是将其转化为(a ±b )2的形式后再化简.由于(a ±b )2=a +b ±2ab ,因此转化的方法就是寻找a ,b ,使得⎩⎪⎨⎪⎧a +b =m ,ab =n ,即a ,b 是方程x 2-mx +n =0的两个根.如化简2-3,首先化为m -2n 的形式,即4-232,解方程x 2-4x +3=0,得x =3或x =1,则4-23=(3-1)2,所以2-3=4-232=(3-1)22=3-12=6-22. 跟踪训练3 化简: 5+26-6-42+7-4 3.随堂水平1.已知x 5=6,则x 等于( ) A . 6 B .56 C .-56 D .±56 2.下列各式正确的是( ) A.(-3)2=-3 B.4a 4=a C.22=2 D.3(-2)3=23.若64a 2-4a +1=31-2a ,则实数a 的取值范围是( )A.(-∞,2)B.⎝⎛⎭⎫12,+∞ C.⎣⎡⎭⎫12,+∞ D.⎝⎛⎦⎤-∞,12 4.计算下列各式的值: (1)3-53=__________;(2)设b <0,则(-b )2=__________. 5.计算: (e +e -1)2-4+(e -e -1)2+4(e≈2.7).参考答案知识导学知识点三 分数指数幂的意义 (2)0 没有意义知识点四 有理数指数幂的运算性质 (1)a r +s (2)a rs (3)a r b r 评价自测1.【答案】(1)√ (2)× (3)√2.【答案】(1)①5a ②4a 3 ③15a 3 ④13a2(2)①(a -b ) 75 ②(a 2-b 2) 34 ③(a 2b -ab 2) 14 ④(a 2-b 2) 24(3)x ≥1核心素养题型一 根式的概念 利用根式的性质化简 例1 (1) (1)【答案】①±45-27 ②76 ③[2,+∞)【解析】①∵(±4)2=16,∴16的平方根为±4.-27的5次方根为5-27. ②∵x 7=6,∴x =76.③要使4x -2有意义,则需x -2≥0,即x ≥2.因此实数x 的取值范围是[2,+∞).
