expand (5+2i)^3+(5-2i)^3

Solution

expand

(5 + 2 i)^{3} + (5 - 2 i)^{3}

Solution

130

Solution steps

(5 + 2 i)^{3} + (5 - 2 i)^{3}

Expand

(5 + 2 i)^{3} : 142 i + 65

= 142 i + 65 + (5 - 2 i)^{3}

Expand

(5 - 2 i)^{3} : - 142 i + 65

= 142 i + 65 - 142 i + 65

Simplify

142 i + 65 - 142 i + 65 : 130

= 130
