![\[\left | 4-3i \right |\]](/tpl/images/0015/0255/14bd1.png)
will be 5.
.
can be calculated as,![\[\left | a-bi \right |\]=\sqrt{a^{2}+b^{2} }](/tpl/images/0015/0255/4df14.png)
![\[\left | 4-3i \right |\]=\sqrt{4^{2}+3^{2} }\\\[\left | 4-3i \right |\]=\sqrt{16+9 }\\\[\left | 4-3i \right |\]=\sqrt{25}\\\[\left | 4-3i \right |\]=5](/tpl/images/0015/0255/7cd61.png)
, here a=4 and b= -3
