Identify the expression to simplify: \$2^{-1} + 4^{-1}$.
Recall that a negative exponent means the reciprocal of the base raised to the positive exponent. So, rewrite each term: \(2^{-1} = \frac{1}{2}\) and \(4^{-1} = \frac{1}{4}\).
Rewrite the expression using these fractions: \(\frac{1}{2} + \frac{1}{4}\).
Find a common denominator to add the fractions. The least common denominator of 2 and 4 is 4, so convert \(\frac{1}{2}\) to \(\frac{2}{4}\).
Add the fractions: \(\frac{2}{4} + \frac{1}{4} = \frac{3}{4}\). This is the simplified expression with no negative exponents.
