Explanation
![9-\sqrt[]{-64}](https://tex.z-dn.net/?f=9-%5Csqrt%5B%5D%7B-64%7D)
Step 1
Let's remember that
A complex number is an object of the form

where a and b are real numbers and
![\begin{gathered} i^2=-1 \\ i=\sqrt[]{-1} \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%20i%5E2%3D-1%20%5C%5C%20i%3D%5Csqrt%5B%5D%7B-1%7D%20%5Cend%7Bgathered%7D)
so
![\begin{gathered} 9-\sqrt[]{-64} \\ 9-\sqrt[]{-1\cdot64} \\ 9-\sqrt[]{-1}\sqrt[]{64} \\ 9-8\sqrt[]{-1} \\ 9-8i \end{gathered}](https://tex.z-dn.net/?f=%5Cbegin%7Bgathered%7D%209-%5Csqrt%5B%5D%7B-64%7D%20%5C%5C%209-%5Csqrt%5B%5D%7B-1%5Ccdot64%7D%20%5C%5C%209-%5Csqrt%5B%5D%7B-1%7D%5Csqrt%5B%5D%7B64%7D%20%5C%5C%209-8%5Csqrt%5B%5D%7B-1%7D%20%5C%5C%209-8i%20%5Cend%7Bgathered%7D)
therefore, the answer is

I hope this helps you
