Modulus of Complex Number

Easy Additional Math Topics Complex Numbers

Consider the complex number $z = 3 + 4i$. To find the modulus of this complex number, use the formula for the modulus of a complex number $z = a + bi$, which is given by:

$$|z| = ext{sqrt}(a^2 + b^2)$$

where $a$ is the real part and $b$ is the imaginary part.

Calculate the modulus of the complex number $z$ and enter the answer in the grid below.
