Question

$sendo \: a\: ( {2}^{3} ) {}^{2} \: \: \: b = {64}^{2} \: c = {16}^{ - 2}$
$calcule \: a \times b \times c$

Answer 1

$Boa \: \: noite!!! \\ \\ a \times b \times c = \\ ( {2}^{3} ) ^{2} \times {64}^{2} \times {16}^{ - 2} = \\ {2}^{6} \times ( {2}^{6} ) ^{2} \times ( {2}^{4} ) ^{ - 2} = \\ {2}^{6} \times {2}^{12} \times {2}^{ - 8} = \\ {2}^{18} \times {2}^{ - 8} = \\ {2}^{10} = 1 \: 024 \\ \\ Espero \: \: ter \: \: ajudado! :)$
