.
- To calculate this expression, let's just:
transform this power with negative exponent into a fraction. Its representation is given by;
[tex] \boxed{ \large \sf a {}^{ - n} \rightarrow \dfrac{1}{a {}^{n} } } \\ \\ [/tex]
Resolution
[tex]{ \large \sf 12 {}^{ - 2} } [/tex]
[tex]{ \large \sf \dfrac{1}{12 {}^{2} } } [/tex]
[tex]{ \large \sf \dfrac{1}{12 \times 12 } } [/tex]
[tex] \red{ \boxed{ \large \sf \dfrac{1}{144 } } } \\ [/tex]
So, the value this expression will be 1/444
