Answer:
0+7i
Step-by-step explanation:
![\sqrt{-49}=\sqrt{49}\sqrt{-1}=7i=\boxed{0+7i}](https://tex.z-dn.net/?f=%5Csqrt%7B-49%7D%3D%5Csqrt%7B49%7D%5Csqrt%7B-1%7D%3D7i%3D%5Cboxed%7B0%2B7i%7D)
The real part of the expression ('a') is zero. We have shown that, so it will be in the required form. Ordinarily, 0 would not be shown when writing this number.

We have taken the question to mean the principal square root. -7i is also a root of -49.
