Okay, here we have this:
Considering the provided expression, we are going to find the requested solution, so we obtain the following:
[tex]\begin{gathered} (\frac{1}{12})^{-2b}\cdot12^{-2b+2}=12 \\ 12^{2b}\cdot12^{-2b+2}=12 \\ 12^{2b-2b+2}=12 \\ 12^2=12 \\ 144=12 \end{gathered}[/tex]
Since the sides are not equal, there is no solution. Therefore the correct option is the fourth option "no solution".
