Answer 1

Answer:

-2/3

Step-by-step explanation:

${(27)}^{ \frac{ - 1}{3} } \times {(27)}^{ \frac{ - 1}{3} } \times ( {27}^{ \frac{1}{3} } - {27}^{ \frac{1}{3} } ) \\ \\ = {3}^{3 \times \frac{ - 1}{3} } \times {3}^{3 \times \frac{ - 1}{3} } \times ({3}^{3 \times \frac{ 1}{3} } - {3}^{3 \times \frac{ 2}{3} } ) \\ \\ = {3}^{ - 1} \times (1/3)\times (3 - 9) \\ \\ = \frac{1}{3} \times (1/3)\times ( - 6) \\ \\ = - 6/9$
