im in math 1314

Hi, Brenda.

Here is an example to further explain:

Suppose you are asked to find the square root of -16. Because there is a negative under the radical, we know we will get an** i
**as part of the answer. The square root of 16 is ±4, so we have

**±**. But this is not in standard form. In standard form (as Roman said earlier), you need a real number part and an imaginary part. Our answer for my example is

*4i***0 ± 4**

*i*Hope this helped.
