Answer:
1
Explanation:
The expression in parentheses is always positive, so raising it to the 0 power gives a value of 1. (Any non-zero value to the zero power is 1.)
Then the expression reduces to ...
10² -99 = 100 -99 = 1
The value of the expression is 1.

Additional comment
The discriminant of the quadratic is ...
b² -4ac = (1/5)² -4(1)(√56) ≈ -29.89
The graph of it is a parabola opening upward. The discriminant indicates the expression has no real zeros, so the graph does not cross the x-axis. It must lie entirely above the x-axis. Hence the quadratic expression is always positive.
