Express each of the following in the form `a+i b :(1/3+3i)^3`

Text Solution

Verified by Experts

The correct Answer is:
N/a
`((1)/(3)+3i)^(3)`
`" "=((1)/(3))^(3)+(3i)^(3)+3*(1)/(3)*3i((1)/(3)+3i)`
`" "=(1)/(27)+27i^(3)+3i((1)/(3)+3i)`
`" "=(1)/(27)+27i(i)^(2)+i+9 i^(2)`
`" "=(1)/(27)-27i+i- 9`
`" "=(-9+(1)/(27))+i(-26)`
`" "=((-243+1)/(27))-26i`
`" "=-(242)/(27)-26i`
