Question

3(в степени 2-х)-(1/3) в степени х+1>26/3

Answer 1

$3^{2-x} - frac{1}{3} ^{x+1} textgreater frac{26}{3}$
$3^{2-x} - 3^{-x-1} textgreater frac{26}{3}$
$3^{3-x} - 3^{-x} textgreater 26$
$3^{-x} ( 3^{3}-1 ) textgreater 26$
$3^{-x} *26 textgreater 26$
$3^{-x} textgreater 1$
$3^{-x} textgreater 3^{0}$
$-x textgreater 0$
$x textless 0$
