(2+i)^3=(i+2)^3 ↝ Properties

(x+y)^3=x^3+3x^2y+3xy^2+y^3\\(i+2)^3=i^3+3(i)^2(2)+3(i)(2)^2+2^3\\(i+2)^3=i^3+6i^2+12i+8

Proceed with define of complex number.

i=\sqrt{-1}\\i^2=-1\\i^3=-i\\i^4=1

-i-6+12i+8\\2+11i

How are fractions and decimals related?
Savatey [412]
Fractions and decimals are related in a very close way. Ways such as they are both representing a whole number. 

for example 

1/2 , 0.5 , 50% 

all three numbers have the same value but are expressed in a different format. all three represent the same whole number. 

another example would be

1/4 , 0.25 , 25% 

hopefully this helped. and or makes sense. 

LET ME KNOW :p
