You tried, basing from your correct use of parentheses, but the two "square" did not help. I assume you did not know yet that "a^2" is the symbol for "a,squared" or "a, square" or "square of a"Quote:

(-1/3)[(1/6)^2]*[(-1/3)(1/6) -(-1/3)^2]
= (-1/3)(1/36)*[(-1/18) -(1/9)]
= (-1/108)*[(-1 +2(-1))/18]
= (-1/108)*[(-3)/18]
= (-1/108)(-1/6)
= 1/648 ------------------answer.
