Question

Distance of complex number z=6+8i from origin is .....unit

Answer 1

Heya,

The distance of z = x + iy from origin is called | z | and is given by $\sqrt{{x}^{2} + {y}^{2} }$

Hence, Distance of z = 6 + 8i from origin =

$\sqrt{ {6}^{2} + {8}^{2} } \\ \\ = > \sqrt{36 + 64 } \\ \\ = > \sqrt{100} \\ \\ = > 10$
