    This is not an equation the "x" means times here. Note the question is in basic math section, so it does not yet involve algebra.
    -----
    First do the parantheses,
    3^4-5\times (10)
    Now do exponents,
    81-5\times 10
    Now do multiplication,
    81-50
    Now you can substract,
    41


    (Note I would like to mention, "order of operations" is not a theorem, it is simply used as a definition. In order to avoid ambiguity).

    Well if breanna007 had only wrote something like "evaluate" or "solve for x" or anything I would know.
