Answer:
8 + i
Step-by-step explanation:
What you need to simplify this is the following "definitions" of i to different powers.




Now we can sub these in for the various powers of i in our expression:

Simplifying a bit:

Since we know that the square root of i-squared is i, and that the square root of 49 is 7, we can get rid of the radial sign as follows:
6 - 6i + 2 + 7i
And the final answer, in a + bi form, is
8 + i
9 and -1 9*-1=-9 and 9-1=8
