The modulus of -8i would be = 8.
How to calculate the modulus of a given figure?
To calculate the modulus of a given figure, the following steps should be taken as follows:
Given z = -8i
The above equestion can be re-written as;
z = 0+(-8i)
Now we have to find the modulus of 0+(-8i)
So,
|z|=. |A0+(-8i)|
= √0²+ -8²
= √64
= 8
Therefore, The modulus of -8i would be = 8.
