b)
${6}^{3} \times {6} =$
c)
$\frac{9}{9} {}^{5} =$
d)8 elevado a 7 /8 elevado 3=

e)
$(7 {}^{2}) {}^{4} =$
f)
${(7}^{8}) {}^{0} =$

​

Answer 1

Resposta:

$a)~4^{3}. 4^{2} =4^{3+2} =4^{5}=1024\\ \\ b)~6^{3}.6=6^{3+1} =6^{4}= 1296\\ \\ c)~\frac{9^{5} }{9} =9^{5-1} =9^{4} =6561\\ \\ d)~\frac{8^{7} }{8^{3} }=8^{7-3} =8^{4} =4096\\ \\ f)~(7^{8} )^{0} =7^{8.0} =7^{0} =1$

$e)~(7^{2} )^{4} =7^{2.4} =7^{8}$
