simplify (sqrt(3)-i)^3

Solution

simplify

(3 - i)^{3}

Solution

- 8 i

Solution steps

(3 - i)^{3}

Apply Perfect Cube Formula:

(a - b)^{3} = a^{3} - 3 a^{2} b + 3 a b^{2} - b^{3}

(3 - i)^{3} = (3)^{3} - 3 (3)^{2} i + 33 i^{2} - i^{3}

= (3)^{3} - 3 (3)^{2} i + 33 i^{2} - i^{3}

Simplify

(3)^{3} - 3 (3)^{2} i + 33 i^{2} - i^{3} : - 8 i

= - 8 i
