please please please d let us kno​

Answer 1

option 2 is right ok........

Answer 2

$log_{9}( \sqrt{3 \sqrt{3 \sqrt{3} } } ) \\ \\ log_{9}(3 \sqrt{3 \sqrt{3} } ) {}^{1 \div 2} \\ \\ (1 \div 2) log_{9}(3 \sqrt{3 \sqrt{3} } ) \\ \\ (1 \div 2) log_{9}(3) + (1 \div 4) log_{9}(3) + (1 \div 8) log_{9}(3) \\ \\ \\ (1 \div 2) log_{3 {}^{2} }(3) + (1 \div 4) log_{3 {}^{2} }(3) + (1 \div 8) log_{3 {}^{2} }(3) \\ \\ \\ (1 \div 2) \times (1 \div 2) \times log_{3}(3) + ( 1 \div 4) \times (1 \div 2) \times log_{3}(3) + (1 \div 8) \times (1 \div 2) log_{3}(3) \\ becoz \: \: log_{x {}^{n} }(y) = (1 \div n) log_{x}(y) \\ \\ (1 \div 4) + (1 \div 8) + (1 \div 16) \\ \\ = 7 \div 16$
