Fractional exponents are just another way to write roots and powers together—the denominator tells you which root, and the numerator tells you the power. The key is to rewrite both 8 and 16 as powers of the same base (2), then use exponent rules to simplify. Once everything is in terms of a single base, adding and subtracting exponents becomes straightforward.
