Answer 1

Resposta:

a)

${2}^{ - 2} \times {5}^{5} \times {2}^{7}$

$\frac{1}{ {2}^{2} } \times 3125 \times 128$

$\frac{400000}{4}$

$100000$

b)

$\frac{ {8}^{2} \times {3}^{6} }{ {6}^{6} }$

$\frac{64 \times 729}{46656}$

$1$

c)

$\frac{ {12}^{3} }{ {6}^{6} }$

$\frac{1728}{46656}$

$0.03$

d)

$\frac{ {3}^{6} \times {4}^{3} }{ {6}^{3} }$

$\frac{729 \times 64}{216}$

$\frac{46656}{216}$

$216$
