(124+22根号3)^(1/2)-27...(124+22根号3)^(1/2)-27^(1/6)+16^(3/4)-2*[8^(-2/3)]^(-1)+2的5次方根*[4^(-2/5)]^(-1)
问题描述:
(124+22根号3)^(1/2)-27...
(124+22根号3)^(1/2)-27^(1/6)+16^(3/4)-2*[8^(-2/3)]^(-1)+2的5次方根*[4^(-2/5)]^(-1)
答
(124+22sqrt(3))^(1/2)=11+gen3
-27^(1/6)=-gen3
+16^(3/4)=8
-2*(8^(-2/3))^(-1)=-8
+2^0.2*(4^(-2/5))^(-1)=2
11+2=13
