resposta: B

Answer 1

$\displaystyle \sf \log_{\ m }\left[\ \log _{ \ m}\left(m^m\right)^{m} \ \right] \\\\\\ \log_{\ m }\left[\ \log _{ \ m}\left(m^{m^2\right) \ \right] \\\\\\ \log_{\ m }\left[\ m^2\cdot \underbrace{\sf \log _{ \ m} (m)}_{1} \ \right] \\\\\\\ \log_{\ m }\left [ m ^2\right ] \\\\ 2\cdot \underbrace{\sf \log_{\ m }[m] }_{1} \\\\\\ \huge\boxed{\sf \ 2 \ }\checkmark$
