Dear student
Since you have not mentioned the question number , so doing as per
my knowledge
We have,logx-13=2⇒log3logx-1=2⇒log3=2logx-1⇒logx-1=log32⇒logx-1=logelog32     as logeθ=θWhen logs have same bases i
e
  logbfx=logbgx⇒fx=gx⇒x-1=elog32⇒x=elog32+1
Please post remaining queries in one thread

Solve this: 122 . 2 x + 2 x ⩾ 2 2 . 123 . 0 . 2 2 x - 3 x - 2 > 5 . 124 . 1 5 2 x + 1 1 - x > 1 5 - 3

Solve this:

$122 . 2^{x} + 2^{|x|} ⩾ 2 \sqrt{2} . 123 . {(0.2)}^{\frac{2 x - 3}{x - 2}} > 5 . 124 . {(\frac{1}{5})}^{\frac{2 x + 1}{1 - x}} > {(\frac{1}{5})}^{- 3}$
