Answer 1

$4^{x+2}*3^{-x}-4^{x}*3^{2-x}\ \textless \ 7*(0,75)^{- \frac{4}{x} }\\ \frac{16*4^x}{3^x} - \frac{9*4^x}{3^x} \ \textless \ 7*( \frac{4}{3} )^ \frac{4}{x} \\ 16*( \frac{4}{3} )^x-9*( \frac{4}{3} )^x\ \textless \ 7*( \frac{4}{3} )^ \frac{4}{x} \\ 7*( \frac{4}{3} )^x\ \textless \ 7*( \frac{4}{3} )^ \frac{4}{x} \\ ( \frac{4}{3} )^x\ \textless \ ( \frac{4}{3} )^ \frac{4}{x} \\ x\ \textless \ \frac{4}{x}/*x\\ x^2-4\ \textless \ 0\\ (x-2)(x+2)\ \textless \ 0\\ x\in(-2;2)$
