Answer:
5
Step-by-step explanation:
Assuming we want to evaluate |z|, given that, z=4+3i.
Then, by definition of modulus,
[tex] |x + yi| = \sqrt{ {x}^{2} + {y}^{2} } [/tex]
[tex]|4+ 3i| = \sqrt{ {4}^{2} + {3}^{2} } [/tex]
[tex]|4+ 3i| = \sqrt{ 16+ 9 } \\ |4+ 3i| = \sqrt{25 } \\ |4+ 3i| = 5[/tex]
Therefore the modulus be of the given complex number is 5 units
