Question

Find the absolute value of the following complex number: |-6-8i|

Answer 1

| - 6 - 8i | = 10

Explanation:

given the complex number a + bi , then the absolute value is

| a + bi | =
`√(a^2+b^2)`

given

- 6 - 8i

with a = - 6 and b = - 8 , then

| - 6 - 8i | =
`√((-6)^2+(-8)^2)` =
`√(36+64)` =
`√(100)` = 10
