Question

find modulus of z=3+4i.

Answer 1

Step-by-step explanation:

To find the modulus of z. |z| = 5. The module of a complex number z = a + i*b is the positive square root of the sum of the squares of the real part, a, and imaginary part, b. The module of the complex number z = 3-4i is |z| = 5

Answer 2

Answer:

5

Step-by-step explanation:

z = 3 + 4i

$|z| = \sqrt{ {3}^{2} + {4}^{2} }$

$|z| = \sqrt{25}$

$|z| = 5$
