помогите решить!!!!!!​

Answer 1

$\displaystyle\frac{ {6}^{ - 4} \times {6}^{ - 9} }{ {6}^{ - 12} } = \frac{ {6}^{ - 4 + ( - 9)} }{ {6}^{ - 12} } = \\ = \frac{ {6}^{ - 13} }{ {6}^{ - 12} } = {6}^{ - 13 - ( - 12)} = \\ = {6}^{ - 13 + 12} = {6}^{ - 1} = \frac{1}{6}$

Answer 2

Решение:

$\tt\displaystyle \frac{6^{-4}*6^{-9}}{6^{-12} } =\frac{6^{-4+(-9)} }{6^{-12}}=\frac{6^{-13}}{6^{-12}}=6^{-13-(-12)}=6^{-1}=\frac{1}{6}$
