-(根号3+i)的15次方怎么解?
-(根号3+i)的15次方怎么解?

-(根号3+i)的15次方怎么解?
(√3+i)^15
=(√3+i)^3^5
=[(3+i^2+2√3i)(√3+i)]^5
=[2(1+√3i)(√3+i)]^5
=[2(√3+4i+√3i^2)]^5
=(8i)^5
=2^15*i

-(根号3+i)^15
=-[2*(根号3/2+i/2)]^15
=-2^15*(cosπ/6+isinπ/6)^15
=-2^15*[cos(15*π/6)+isin(15*π/6)]
=-2^15[cos(5*π/2)+isin(5*π/2)]
=-2^15[cos(π/2)+isin(π/2)]
=-2^15*(0+i)
=-2^15*i

(根3+i)^6=((3-1+2根3*i)(根3+i))^2=(2(1+根3*i)(根3+i))^2
=4(根3+i+3i-根3)^2=-64
(根号3+i)^12=2^12
(根号3+i)^3=8i
原式=-2^15*i
