Answer»

Answer:

USING the identity,

{ ({a}^{m} )}^{n} = {a}^{mn}

So, the answer PROCEEDS as,

{ { { (\frac{8}{9}) }^{ - 2} }^{ \frac{1}{3} } }^{6} = {( \frac{8}{9} )}^{ - 2 \times 6 \times \frac{1}{3} } = {( \frac{8}{9}) }^{ - 4}

= {( \frac{9}{8})}^{4} = \frac{729}{512}

Plz mark me as the brainliast.
