Hope u like my process..
-------------------------------------
${2}^{3} ( {5}^{0} + {3}^{2x} ) = 8 \frac{8}{27} \\ or. \: {2}^{3} (1 + {3}^{2x} ) = 8 + \frac{8}{27} \\ or. \: {2}^{3} + {2}^{3} \times {3}^{2x} = {2}^{3} + {2}^{3} \times {3}^{ - 3} \\ \\ thus \: by \: comparing \: we \: get \: .. \\ 2x = - 3 \\ or. \: x = - \frac{3}{2}$
