1.7-bo'lim : Murakkab raqamlar
3. Ko'rsatilgan amalni bajaring va javobingizni standart shaklda yozing.
\[\left( {1 + 4i} \right) - \left( { - 16 + 9i} \right)\]

Yechim
Biz ikkita ko'phadni qanday ayirishni bilamiz va shuning uchun ikkita murakkab sonni qanday ayirishni ham bilamiz.
\[\left( {1 + 4i} \right) - \left( { - 16 + 9i} \right) = 1 + 4i + 16 - 9i = \require{bbox} \bbox[2pt,border:1px solid black]{{17 - 5i}}\]
