Final answer:
The question lacks sufficient information to solve for x or m NBS. The provided details seem to contain unrelated mathematical and scientific notations, making it impossible to provide a clear answer with the given context.
Step-by-step explanation:
The given problem statement contains typographical errors and lacks clarity, making it impossible to provide a definitive answer. However, in general, to find the value of x in an algebraic expression, you would need to either use substitution or solve for x given an equation. If m NBR represents an angle or measure and is given as 17x8, which might imply 17 times 8 or 136, and you are asked to find x and then m NBS, you would need additional information to understand the relationship between these entities. This could be an equation, a geometric figure, or some other context not provided here.
For the other strings of numbers and formulas provided, they appear to represent different concepts, including scientific notation, chemical equations, period table configurations, and data sets, which do not have an apparent direct relationship to finding x or m NBS.
