​

Answer 1

$\huge\mathfrak\red{\star{\underline{\underline{Answer}}}}$

❥ $\Large{{(\frac{-2}{7})}^{2x}× {(\frac{2}{-7})}^{1} = {(\frac{-2}{7})}^{3}}$

❥ $\Large{{(\frac{-2}{7})}^{2x}×{(\frac{-2}{7})}^{1}={(\frac{-2}{7})}^{3}}$

$\large\mathcal\pink{Equating\: the\: powers}$

❥$2x+1 =3$

❥ $\cancel{2}x= \cancel{2}$

❥ x = 1
