(3+2√2)的十次方乘以(1-√2)的十九次方+(√2+1)的负一次方减(2√2减3)的零次方
求完整详细过程或思路,
(3+2√2)的十次方乘以(1-√2)的十九次方+(√2+1)的负一次方减(2√2减3)的零次方求完整详细过程或思路,
(3+2√2)^10*(1-√2)^19+(√2+1)^-1-(2√2-3)^0
=(3+2√2)^10*(1-√2)^19+(√2+1)^-1-1
=(√2+1)^20*(1-√2)^19+(√2+1)^-1-1
=(√2+1)*(√2+1)^19*(1-√2)^19+(√2+1)^-1-1
=(√2+1)*[(√2+1)(1-√2)]^19+(√2+1)^-1-1
=(√2+1)*(-1)^19+(√2+1)^-1-1
=-(√2+1)+1/(√2+1)-1
=-(√2+1)+(√2-1)/(√2+1)(√2-1)-1
=-(√2+1)+(√2-1)-1
=-√2-1+√2-1-1
=-3
很简单啊。。主要是凑起来就好了。答案-2√2减1
(3+2√2)^10*(1-√2)^19+1/(√2+1)-(2√2-3)^0 =
(3+2√2)^10*(1-√2)^20/(1-√2)+1/(√2+1)-(2√2-3)^0 =
(3+2√2)^10*(3-2√2)^10/(1-√2)+1/(√2+1)-(2√2-3)^0 =
(1)^10/(1-√2)+1/(√2+1)-(2√2-3)^0 =
-1-√2+√2-1-1= -3
(3+2√2)^10*(1-√2)^19+(√2+1)^(-1)-(2√2-3)^0=(3+2√2)^10*(3-2√2)^10*(1-√2)^(-1)+(√2+1)^(-1)-1=(1-√2)^(-1)+(√2+1)^(-1)-1=-(√2+1)+√2-1-1=-3
