B -
$10 {}^{ - 1}$
C-
$(5 + 3) {}^{2} = {8}^{2} = 64$
D-
${4}^{3} \times 4 \times {4}^{2} = {4}^{6}$
E-
$( \frac{2}{3} ) {}^{ - 2} = ( \frac{3}{2} ) {}^{2} = \frac{9}{4}$

respostas: C

Answer 2

Resposta: Alternativa C

$a)( {8}^{3} ) ^{2} = 8 ^{(3 \times 2)} = {8}^{6} \\ \\ b) ( \frac{ {10}^{4} }{ {10}^{5} } ) = 10 ^{(4 - 5)} = {10}^{ - 1} \\ \\ c)(5 + 3) ^{2} = {8}^{2} = 64 \\ \\ d) {4}^{3} \times 4 \times {4}^{2} = 4 ^{(3 + 1 + 2)} = {4}^{6} \\ \\ e)( \frac{2}{3} ) ^{ - 2} = ( \frac{3}{2} ) ^{2} = \frac{9}{4}$
