Question

Find the absolute value.
|-7+5i
V[?]

Answer 1

`√(74)`

Explanation:

The absolute value of a complex number a+bi is equal to
`√(a^2+b^2)`. In this example, we have a = -7 and b = 5. Now, it's just a matter of plugging these values in. We would get
`√((-7)^2+5^2)`, which simplifies to
`√(49 + 25)`, which is equal to
`√(74)`.
