Given the definition of two new operators, evaluate an expression that contains that operator.

Problem

The operations \barwedge and \odot are defined as follows:
  • xy=2x2y2x \barwedge y = 2x^{2}-y^{2}
  • xy=x23y2x \odot y = x^{2}-3y^{2}
Find 0(31)0 \barwedge (3 \odot 1).
  • Your answer should be
  • an integer, like 6
  • a simplified proper fraction, like 3, slash, 5
  • a simplified improper fraction, like 7, slash, 4
  • a mixed number, like 1, space, 3, slash, 4
  • an exact decimal, like 0, point, 75
  • a multiple of pi, like 12, space, p, i or 2, slash, 3, space, p, i
