Penjelasan dengan langkah-langkah:
[tex]1) \frac{ {2}^{3} \times {2}^{4} }{ {2}^{6} } = \frac{ {2}^{3 + 4} }{ {2}^{6} } = \frac{ {2}^{7} }{ {2}^{6} } = {2}^{7 - 6} = {2}^{1} = 2[/tex]
[tex]2){( - \frac{2}{3} )}^{ - 2} = ( \frac{3² \times 1}{{2}^{2} } ) = ( \frac{9}{4} )[/tex]
[tex]3) \: 3x = 245 \\ x = \frac{245}{3} [/tex]
