Determine 3888

Determine the sum of the three-third roots of the number 64.

Correct answer:

x =  0

Step-by-step explanation:

u=2π/3=2 3.1416/32.0944 x1=364=4 y1=0 x2=x1 cosu=4 cos2.0944=2 y2=x1 sinu=4 sin2.0944=2 33.4641 x3=x1 cos(2 u)=4 cos(2 2.0944)=2 y3=x1 sin(2 u)=4 sin(2 2.0944)=2 33.4641 x=x1+x2+x3=4+(2)+(2)=0 y=y1+y2+y3=0+3.4641+(3.4641)=0
