Answer 2

Resposta:

a) 8

b) 3125

c) 9

d) 49

Explicação passo-a-passo:

$a)\:\:\frac{\diagup\!\!\!\!\!32^{\div32}\times16 }{\diagup\!\!\!\!\!64^{\div32}} =\frac{16}{2} =\boxed{8}$

$b)\:\frac{\diagup\!\!\!\!\!\!\!\!625^{\div25}\times125}{\diagup\!\!\!\!\!25^{\div25}} =25\times125=\boxed{3125}$

$c)\frac{\diagup\!\!\!\!81^{\div81}\times27}{\diagup\!\!\!\!\!\!243^{\div81}} =\frac{27}{3} =\boxed{9}$

$d)\frac{\diagup\!\!\!\!\!\!343^{\div49}\times7}{\diagup\!\!\!\!\!49^{\div49}} =7\times7=\boxed{49}$
