    First remember that the priorities of operations are:
    1. exponentiation
    2. multiplication & division
    3. addition and subtraction
    and parentheses are before all of the above, from inside out.
    So
    2×3^3+4
    would mean
    (2×(3^3))+4

    For the given problem, these are these possibilities:

    (2×3)^3+4
    2×(3^3)+4
    2×3^(3+4)
    (2×3)^(3+4)

    Check out each of them. If you don't find one that fits the bill, you probably have not followed the priority of operations. In that case, post again.
