plz answer the question no.2​

Answer 1

$heya \\ \\ \\ 343 = 7 {}^{3} \\ \\ and \\ \\ log(x {}^{n} ) = n log(x) \\ \\ \\ \\ \\ = > \\ \\ \\ \\ 7 {}^{ - 3} = 3 {}^{c} \\ \\ \\ \\ taking \: log \: on \: both \: sides \\ \\ \\ log(7 {}^{ - 3} ) = log(3 {}^{c} ) \\ \\ \\ - 3 log(7) = c log(3) \\ \\ \\ - 3 \times log(7) \div log(3) = c$
