To simplify the expression ( 14ab^3 + 7a^{-2}b^{-1} ), we can express it with positive exponents. The term ( 7a^{-2}b^{-1} ) can be rewritten as ( \frac{7}{a^2b} ). So the expression becomes ( 14ab^3 + \frac{7}{a^2b} ). Since these two terms do not have a common factor, this is the simplest form of the expression.
