Question

How do you find the absolute value of 3+4i?

Answer 1

`|a + bi|` is not read as the absolute value of `a + bi`; it is read as the magnitude of `a + bi`:

`|3 + 4i| = sqrt(3^2 + 4^2)` = 5

Explanation:

The |a + bi| is not read as the absolute value of a + bi; it is read as the magnitude of a + bi. The magnitude is calculated, using the equation:

`|a + bi| = sqrt(a^2 + b^2)`

`|3 + 4i| = sqrt(3^2 + 4^2)` = 5
