Calculating the Modulus of a Complex Number

Very Easy Additional Math Topics Complex Numbers

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

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

where $z = a + bi$. Calculate the modulus of $z$ and provide your answer as a grid-in response.
