## mathslover 2 years ago Can |x| ever be negative in any case?

1. mukushla

nope

2. Libniz

yes

3. Libniz

|x| can't

4. mathslover

|i| is negative or positive

5. mukushla

=1 is positive

6. jmodel12

Absolutely! My X is negative 50% of the time.

7. chandhuru

modulus i is positive

8. mathslover

$|\sqrt{-1}| = ?$ 0^2 + 1^2 = 1 ?

9. mukushla

$\text{magnitude of everything}\ge0$

10. mathslover

|(a+ib)^2| = a^2+b^2 ?

11. mathslover

|a+ib|^2 = a^2+b^2

12. hartnn

|a+ib| = sqrt(a^2+b^2)

13. mathslover

Yep.. Thanks @mukushla and @Libniz and @hartnn

14. mukushla

no problem

no because |x| = √(X² ) so even if you get any number + or - the number will be squared first making it to be + then it will be rooted to give you the number
