.

• To calculate this expression, let's just:

transform this power with negative exponent into a fraction. Its representation is given by;

$\boxed{ \large \sf a {}^{ - n} \rightarrow \dfrac{1}{a {}^{n} } }$

Resolution

${ \large \sf 12 {}^{ - 2} }$

${ \large \sf \dfrac{1}{12 {}^{2} } }$

${ \large \sf \dfrac{1}{12 \times 12 } }$

$\red{ \boxed{ \large \sf \dfrac{1}{144 } } }$

So, the value this expression will be 1/444
