(-3/3/8)^-2/3+(0.002)^-1/2-10(根号5-2)^-1+(根号2-根号3)^0
(-3/3/8)^-2/3+(0.002)^-1/2-10(根号5-2)^-1+(根号2-根号3)^0
(-3/3/8)^-2/3+(0.002)^-1/2-10(根号5-2)^-1+(根号2-根号3)^0
(-3/3/8)^-2/3+(0.002)^-1/2-10(√5-2)^-1+(√2-√3)^0
=(-27/8)^-2/3+(1/500)^-1/2-10(√5-2)^-1+1
=(8/27)^2/3+√500-10/(√5-2)+1
=[(2/3)^3]^2/3+10√50-10(√5+2)/(√5+2)(√5-2)+1
=(2/3)^2+10√5-10(√5+2)+1
=4/9+10√5-10√5-20+1
=-18又9分之5
