Question

please solve this both sums please​

Answer 1

21). take exponential on both the sides and you will find x.

22) just take the LCM and then add and just simplify it

Answer 2

$heya \\ \\ log_{ \sqrt{27} }(x) = 2 + 2 \div 3 \\ \\ log_{3 {}^{3 \div 2} }(x) = 8 \div 3 \\ \\ (2 \div 3) log_{3}(x) = 8 \div 3 \\ \\ log_{3}(x) = 4 \\ \\ x = 3 {}^{4} \\ \\ x = 81$
