Answer 2

Answer:

$(-3)^{-3} =  (\frac{-1}{27} )$

Step-by-step explanation:

Consider LHS $(-3)^{-3}$

As we know, $(a)^{-b}  = \frac{1}{a^{b} }$

That is how, we make the exponents positive.

Taking reciprocal of the numerator,

we get  $(-3)^{-3}$  = $\frac{1}{(-3)^{3} }$

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

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