To simplify the expression, we can multiply the numerators and denominators together:

(-17/81) × (-5/34) × (-9/5) = (17 * 5 * 9) / (81 * 34 * 5)

Now, we can cancel out common factors:

(17 * 5 * 9) / (81 * 34 * 5) = (17 * 9) / (81 * 34)

= 153 / 2754

Therefore, -(17/81) × (-5/34) × (-9/5) = 153 / 2754.
