3^-2=() (1/3)^-2=
3a^-2=() (3a)^-2=
(-x³)²÷(-2)²·(-x)³
-2^0-(-1/2)^4÷(-1/2)^-2·(-1/2)^-3
-2³+(π-3.14)^0-1÷(-1/2)^-1
下面的也要过程:
3^m=6,3^n=5,求3^m-n; 3^3m-2n
4^m·8^m-1÷2m=512,求M
10^a=20 10^b=5^-1
求9^a÷3^2b的值
初一整式除法的.来做啊x-0)^0=() (-1)^0= 3^-2=() (1/3)^-2= 3a^-2=() (3a)^-2= (-x³)²÷(-2)²·(-x)³ -2^0-(-1/2)^4÷(-1/2)^-2·(-1/2)^-3 -2³+(π-3.14)^0-1÷(-1/2)
x-0)^0=(1) (-1)^0= 1
3^-2=(1/9) (1/3)^-2=9
3a^-2=(3/a^2) (3a)^-2= 1/9a^2
这个要过程了:
(-x³)²÷(-2)²·(-x)³
=x^6 ÷4*(-x)^3
=-x^9/4
-2^0-(-1/2)^4÷(-1/2)^-2·(-1/2)^-3
=1-1/16÷4*(-8)
=1+1/8=9/8
-2³+(π-3.14)^0-1÷(-1/2)^-1
=-8+1-1÷(-2)
=-15/2
下面的也要过程:
3^m=6,3^n=5,求3^m-n; 3^3m-2n
3^m-n=3^m/3^n=6/5
3^3m-2n
=3^3*3^m/3^2*3^n
=3^3*6/3^2*5
=18/5
4^m·8^m-1÷2m=512
4^m·2^m-1*4^m-1÷2m=512
4^2m*2^m-m-1=512
4^2m-1*2^-1=512
(16)^m=512*8
m=3
9^a÷3^2b
=(3^2)^a÷3^2b
=3^2)^a-b
10^a=20 10^b=5^-1
10^a/ 10^b=20/5^-1
10^a-b=20/5^-1
a-b=2代入
=(3^2)^2
=81
