Answer 1

Heya

_________________________

$log_{4 \div 5}(4 {}^{3} \div 5 {}^{3} ) + log_{4 \div 5}(1) \\ \\ \\ log_{4 \div 5}(4 {}^{3} \div 5 {}^{3} \times 1 ) \\ \\ \\ \\ \\ 3 log_{4 \div 5}(4 \div 5) \\ \\ \\ \\ 3 \times 1 \\ \\ \\ = 3$

Answer 2

$log_{ \frac{4}{5} }( \frac{64}{125} ) \\ = \: log_{ \frac{4}{5} }( (\frac{4}{5}) {}^{3} ) \\ = 3log_{ \frac{4}{5} }( \frac{4}{5} ) \\ = 3$

as

$log_{ \frac{4}{5} }(1 ) = 0$

so the and is 3
