Well, this is a good practice of indices.
All of the numbers involved have the same base.
so, for the inner bracket, the powers will be (division is a minus sign for the powers):
So the inner value is

Use the quadratic formula, x=
(don't know how to type the "-"sign in the formula, so there is only the "+" in the formula)
in this case, a=1, c=34, b is unknown
from the roots, we can tell that -b+
=2(5+3i)=10+6i
Note: the original equation already give b as -b, so -(-b)=10, b=10
using b^2-4ac=(6I)^2,
b^2-4*34=-36
b^2=100
you will also get b=10
