  1. Since we have parentheses around the
    negative three here, and the exponent, the
  2. four is written outside of those
    parentheses, that means that the exponent
  3. applies to the entire quantity that's
    inside the parentheses. So, the number
  4. that counts as the base number is negative
    three. Negative three is the thing that we
  5. want to multiply by itself four times. So
    that means we can rewrite this as
  6. -3-3-3*-3.
    Now we can just evaluate that numerically.
  7. -3*-3 is just positive nine, so we get
    positive nine multiplied by itself, which
  8. is just equal to 81. So our final answer
    is 81.
