Answer 2

Answer:

The value of equation is $-6/9$.

Step-by-step explanation:

The equation is given as $(27) ^{-1/3} (27) ^{-1/3} [(27) ^{1/3} - (27) ^{2/3} ]$

We need to evaluate it.

As $27$ is cube of $3$.

$3^{3}$

Hence

$(27) ^{-1/3}=\frac{1}{3}$

$(27) ^{1/3}=3$

$(27) ^{2/3}=9$

The equation becomes $\frac{1}{3} \frac{1}{3} (3-9)=\frac{-6}{9}$

So the value of equation is $-6/9$.
